Objective: Humeral tuberosity cysts are a common finding, with previous reports suggesting they are related to rotator cuff tear or aging. The suprascapular nerve was retracted gently, and curettage was performed until the bone surrounding the cyst was completely exposed (Figure 3(d)). The area at which the patient experienced spontaneous shoulder pain was innervated by the suprascapular nerve, and 1% xylocaine injection into the spinoglenoid notch under ultrasonographic guidance relieved the pain. A skin incision of approximately 10 cm was made along the glenoid on the lateral side of the scapula. Additionally, the previously reported case of an intraosseous ganglion accompanied with suprascapular nerve entrapment was treated with needle aspiration under arthroscopy [9], and posterior shoulder pain and muscle strength weakness of the shoulder resolved. Abstract Intraosseous ganglia are benign cystic and often multiloculated lesions composed of fibrous tissue with extensive mucoid changes located in the subchondral bone adjacent to … Epidemiology Tends to occur in middle age. An intraosseous ganglion/ cyst, however, is not common and is limited to the hip, knee, and ankle.5 In particular, an intraosseous ganglion of the glenoid is extremely rare, and no study to date has reported on an intraosseous glenoid ganglion /cyst. The exact cause of ganglion cysts in shoulder is not known. However, if the cyst is inside the shoulder joint certain tests such as ultrasound, MRI, may be required for its diagnosis. Although the cyst develops commonly on the palmar side or dorsal of wrist joint, sometimes this tumor like lump can also grow over elbow, knee, hip, ankle and shoulder. The site was then injected with a small amount of demineralized bone matrix. (a) Clinical photograph before the surgery shows a dotted circle at the left shoulder that indicates the area at which the patient complained of pain. An intraosseous ganglion (plural: ganglia) is a benign subchondral radiolucent lesion without degenerative arthritis. The cyst is just underneath the skin near a joint. These cysts are produced in areas of damaged articular cartilage, subjacent to the underlying subarticular cortical plate. The exact reason why a ganglion develops in shoulder is not known. As a result, we could perform curettage of the cyst wall, which relieved the patient of the symptom. Certain factors increase the risk of ganglion cysts. Postoperatively, the patient's shoulder pain resolved promptly. We believe that open surgery including curettage is a useful treatment option for a ganglion inside bone and present very close to the suprascapular nerve. Only 13 cases around the shoulder have been described in the literature. Intraosseous ganglia are rare lesions that can cause pain and leave patients susceptible to pathologic fracture. The patient was a 47-year-old woman with a painful left shoulder with a limited range of motion. Second edition by Lippincott Williams & Wilkins. Annals Of Orthopaedics, Trauma And Rehabilitation. However, the ganglion relapsed at the 1-year follow-up on MRI, suggesting that curettage for the ganglion was inadequate and en bloc resection would be necessary if the symptoms of the left shoulder recur. Subchondral bone cysts (SBCs) are sacs filled with fluid that form inside of joints such as knees, hips, and shoulders. Recently, a simple and safe less invasive arthroscopic approach was reported for patients with spinoglenoid ganglion cysts [11]. 2017, Article ID 1704697, 5 pages, 2017. https://doi.org/10.1155/2017/1704697, 1Department of Orthopaedic Surgery, Gifu University School of Medicine, Yanagido 1-1, Gifu, Gifu Prefecture, Japan. The patient was a 61-year-old woman with a painful left shoulder with a limited range of motion. Review articles are excluded from this waiver policy. Few reports have presented the characteristics of an intraosseous ganglion, such as its incidence and etiology, and this ganglion is considered to be relatively rare. Suprascapular nerve entrapment is an uncommon but significant cause of shoulder pain [1], and a ganglion originating from the soft tissues around the spinoglenoid notch has been reported to be a cause of suprascapular nerve entrapment [2]. … In our case, we used curettage and did not consider arthroscopic treatment for various reasons. Histological examination revealed that the cyst wall contained connective tissue, including collagen fibers and a few fibroblasts, and that the inner layer of connective tissue exhibited myxoid change (Figures 4(a) and 4(b)). (a, b) Microscopic section of the cyst wall shows that the wall contained connective tissue, including collagen fibers and a few fibroblasts, and that the inner layer of connective tissue had myxoid change. @article{Yi2009IntraosseousGO, title={Intraosseous ganglion of the glenoid causing suprascapular nerve entrapment syndrome: a case report. The exact reason why a ganglion develops in shoulder is not known. 3-5cm, bulging, with a white outer fibrous surface, usually multilocular. Histological examination revealed that the cyst wall contained connective tissue, including … The fluid is sticky, jelly like colorless substance. Up to 7cm in size, usu. This fluid is similar to the fluid that found in joints to keep it lubricated. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. They often recede in the size and sometimes disappear. The extraosseous cyst extended to the intraosseous lesion directly. A lipoma is a slow-growing, fatty lump that's most often situated between your skin and the underlying muscle layer. Epidemiology Tends to occur in middle age. It is more prevalent in men. We reported a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch, which is a rare cause of posterior shoulder pain. Additionally, the previously reported case of an intraosseous ganglion accompanied with suprascapular nerve entrapment was treated with needle aspiration under arthroscopy [9], and posterior shoulder pain and muscle strength weakness of the shoulder resolved. Commonly these lesions are found just beneath the attachments of the cruciate ligaments and are frequently associated with similar appearing soft-tissue ganglia nearby or with additional intraosseous ganglia in the vicinity [2]. A 47-year-old man with left shoulder pain developed an intraosseous cyst in the left glenoid, which came into contact with the suprascapular nerve. On visiting our hospital, he complained of continuous posterior shoulder pain at rest; however, he could move his shoulder actively at 160 degrees of flexion and abduction, 60 degrees of external rotation at the side, and 90 degrees of external rotation at abduction and could maintain muscle strength around the shoulder on manual muscle testing. with intraosseous ganglia of carpal bones. Only 13 cases around the shoulder have been described in the literature. It passes between the suprascapular notch and superior transverse scapular ligament into the posterior surface of the scapula, which dominates the supra- and infraspinatus muscles. This article describes an arthroscopic technique used for lunate intraosseous cyst resection associated with an autologous bone graft in a series of cases to prevent joint stiffness while respecting the scapholunate ligament. }, author={Jin Woong Yi and Nam Su Cho and Y. Rhee}, journal={Journal of shoulder and elbow surgery}, year={2009}, volume={18 3}, pages={ e25-7 } } please consult your Orthopedician he will examine and treat you accordingly. We present the first reported case of complete, spontaneous resolution of a massive AC joint cyst without the need for surgical intervention. Sign up here as a reviewer to help fast-track new submissions. First, based on the radiographic finding of bone cortex destruction at the spinoglenoid notch, the differential diagnosis included an intraosseous ganglion, giant cell tumor, aneurysmal bone cyst, and chondroblastoma [12, 13], so we needed a specimen to perform histological examination. Notice the intermediate signal within the cyst, suggestive of pannus invasion. pain is due to an intraosseous bone ganglion cyst. Plain radiographs show an eccentric intraosseous radiolucent lesion that should be differentiated from osteoarthritic cyst, post-traumatic cyst, simple bone cyst, osteoid osteoma, or osteoblastoma. The spinoglenoid notch was directly visualized after splitting the teres minor and infraspinatus muscles, and the suprascapular nerve and cyst were identified at the spinoglenoid notch (Figure 3(b)). (b) MR T2-weighted sagittal image of the left shoulder shows that the intraosseous lesion is linked to the spinoglenoid notch. Up to 7cm in size, usu. He did not show sensory and motor paralysis of the supra- and infraspinatus muscles and did not exhibit muscle atrophy on visual examination. May extend through the cortex into the joint, esp. Skeletal Radiol 25:588-91,1996. Author information: (1)Department of Orthopaedic Surgery, University of Göttingen, Medical Center, UMG, Germany. These lesions are often asymptomatic, but, in cases located close to neurovascular structures or articular surfaces, they can be symptomatic, causing pain, neurologic dysfunction, or articular fractures. Ways to Stop This Pain, Causes of Hiccups at Night During Pregnancy: How Do You Stop It, There are several conditions that begin with fever as the only symptom. This report represents the first published case of an intraosseous foreign body gran-uloma in the humeral head after arthroscopic rotator cuff tear fixation with a poly-L-lactide (PLLA) suture anchor. This study was based on a series of 4 patients, all of whom had wrist pain because of intraosseous ganglion cysts. Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. It has a stalk through which fluid enters in the lump. Two main types of periarticular cysts are frequently seen on shoulder MRI, both of which have a strong association with underlying abnormalities. Tham S, Ireland DC: Intraosseous ganglion cyst of the lunate: diagnosis and management. Design and patients: Shoulder MR arthrograms were reviewed in 120 consecutive patients-83 males (mean age 38.0, range 19-59 years) and 37 females (mean age 41.2, range 15-59 years). even described an intraosseous rheumatoid nodule with avidity for gallium-67 citrate in the rib of a 9-year-old boy with rheumatoid nodulosis. A small incision was made in the anterior shoulder, the cyst site was identified due to a small hole noticed in the bone deep to bicep tendon. dysfunction caused by an intraosseous ganglion of the glenoid is extremely rare, to the best of our knowledge, only 1 case of suprascapular nerve entrapment due to an intraosseous ganglion cyst has been reported previously in the published literature. These cysts should be considered causes of unexplained rotator cuff weakness in young patients, although they may also be discovered incidentally on MRI. as cyst formation, soft-tissue inflammation, loose implant fragments or local osteolysis. Pain relievers may be beneficial in alleviating shoulder pain. However, suprascapular nerve entrapment caused by an intraosseous ganglion occurring in the glenoid is rare.

All the authors certify that they have no commercial associations that might pose a conflict of interest in connection with this report. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. But this may be a temporary and soon the pain occurs once the medicines are stopped. Sclerotic lesions are spots of unusual thickness on your bones. Objective: To present the diagnostic and clinical features of an intraosseous ganglion cyst of the humeral head of a female flat water canoe athlete. The area includes the supra- and infraspinatus muscles and the suprascapular nerve. The patient gave informed consent and permission for this publication. Annals Of Orthopaedics, Trauma And Rehabilitation 03 Arthroscopic Management of an Intraosseous Ganglion Cyst in the Prox imal Tibia. 28-194). This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. These lesions are often asymptomatic, but, in cases located close to neurovascular structures or articular surfaces, they can be symptomatic, causing pain, neurologic dysfunction, or articular fractures. A lipoma, which feels doughy and usually isn't tender, moves readily with slight finger pressure. Ganglion cyst in shoulder is not common, but when present can produce discomforting pain and weakness in shoulder. The area at which he experienced spontaneous shoulder pain was innervated by the suprascapular nerve (Figure 1(a)). Intraosseous ganglia within the carpal bones are relatively rare, with only a limited number of cases previously reported (1–3).They are benign, non-neoplastic bone lesions that have similar histological characteristics to those of soft tissue ganglion cysts (4,5).The most common clinical symptom is wrist pain. Abstract We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. The suprascapular nerve is a mixed motor and sensory nerve originating from the brachial plexus. Intraosseous ganglia are uncommon in skeletal sites such as the carpal bones, wrist, proximal femur, distal tibia, and glenoid bone. Curettage was performed under general anesthesia in the right lateral position (Figure 3(a)). A subchondral cyst (Fig. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. However, ganglion cysts in shoulder may … A subchondral cyst is an intraosseous epiphyseal synovial fluid-filled void prevalent in osteoarthritis that may attain a diameter of 1-15 mm or more in size with the cyst’s longest axis usually along the coronal plane in the craniocaudal axis. However, ganglion cysts in shoulder may sometimes become large and compress the nerve which may give rise to pain and difficulty in movement. West Indian Med J 54:247-9,2005. The nerve was stretched and edematous, and it highly adhered to the cyst wall. We performed curettage with protection of the suprascapular nerve, and the patient’s pain resolved completely without suprascapular nerve complications. Intraosseous ganglion cysts are rare causes of wrist pain. Intraosseous ganglia are uncommon in skeletal sites such as the carpal bones, wrist, proximal femur, distal tibia, and glenoid bone. The histological finding was an inner layer of fibrous connective tissue without any lining cells. Intraosseous ganglion cyst of the carpal bones represents a rare cause of wrist pain. More often than not, paralabral cysts of the shoulder are an infrequent finding on MRI or MR Arthrogram. Osteoarthritis and rheumatoid arthritis can lead to the development of these cysts… An extraosseous cyst was located over the posterior glenoid neck, which had capsules filled with a transparent gelatinous substance. Lipomas are usually detected in middle age. The most common is the paralabral cyst that results from a glenoid labral tear . Postoperatively, the patient’s shoulder pain resolved promptly. The common stalk feeds fluid into the tumor-like mass. MRI of the shoulder has proven to be an accurate noninvasive examination for the evaluation of patients with shoulder pain. Therefore, in the present case, it was believed that the ganglion did not occur in the soft tissue around the spinoglenoid notch and then penetrate into the glenoid, but it occurred primarily inside the glenoid and protruded into the spinoglenoid notch accompanied with bone destruction over a long period. Intraosseous ganglion cyst References [1] Adam Greenspan, Gernot Jundt , Wolfgang Remangen (2007) Differential diagnosis in orthopaedic oncology. Figure 3: MRI of the knee joint T2 Image (a) and (b) showing periarticular intraosseous cyst. Copyright © 2017 Daichi Ishimaru et al. To date, these lesions have been treated with curettage and bone grafting through an open approach, although more recent techniques have allowed arthroscopic treatment of lesions located at the wrist, knee, and ankle. ... Intraosseous operation - resection of the cyst with parallel bone graft and application of Ilizarov's apparatus. A. Slullitel, “Juxta-articular bone cysts (intra-osseous ganglia): a clinicopathological study of eighty-eight cases,”. An intraosseous ganglion (plural: ganglia) is a benign subchondral radiolucent lesion without degenerative arthritis. Patients suffering from paralabral cyst have chronic shoulder pain as the chief complaint. Intraosseous ganglia are uncommon in skeletal sites such as the carpal bones, wrist, proximal femur, distal tibia, and glenoid bone. This compression can result in atrophy of the supraspinatus or infraspinatus muscle or both. These findings were consistent with an intraosseous ganglion. J Hand Surg 17B:429-32,1992. We experienced a rare case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. Only 13 cases around the shoulder have been described in the literature. 3-5cm, bulging, with a white outer fibrous surface, usually multilocular. (c) Intraoperative photograph shows a mucinous cyst wall after shifting the suprascapular nerve laterally. A ganglion cyst is diagnosed during physical examination if it is on the shoulder. Two main types of periarticular cysts are frequently seen on shoulder MRI, both of which have a strong association with underlying abnormalities. To our knowledge, 19 cases of intraosseous ganglion of the glenoid have been reported in the English literature [4–10]. (d) Intraoperative photograph shows the bone cavity of the glenoid after curettage of the cyst (yellow arrowheads). The suprascapular nerve was raised upward by the cyst wall present below the nerve. Furthermore, in surgery, we could identify the intraosseous cyst and suprascapular nerve and protect the nerve under direct vision; nevertheless, the intraosseous cyst compressed the nerve and adhered to it causing edema. A ganglion cyst is diagnosed during physical examination if it is on the shoulder. Intraosseous ganglion cysts are benign lesions located in the subchondral bone adjacent to the joint and are usually found in adults [1]. Magnetic resonance imaging (MRI) showed an osteolytic cystic lesion with very high intensity on T2-weighted images and low intensity on T1-weighted images, and the lesion was located at the posterior cranial portion of the glenoid and partially extended to the spinoglenoid notch (Figures 2(a) and 2(b)), and there were no findings about fatty change and intramuscular edema in supra- and infraspinatus muscles. We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. }, author={Jin Woong Yi and Nam Su Cho and Y. Rhee}, journal={Journal of shoulder and elbow surgery}, year={2009}, volume={18 3}, pages={ e25-7 } } Ganglion cysts typically form within deep tissue as one or a cluster of smaller cysts connected by a common stalk. Clinical Features: An 18-year old female flat water canoeist complaining of right shoulder pain following a strenuous paddling training camp. INTRAOSSEOUS GANGLION. The yellow arrow indicates the myxoid area, and the yellow arrowheads show connective tissue, including collagen fibers and a few fibroblasts (hematoxylin and eosin staining; A: ×12.5 magnification, B: ×50 magnification). Intraosseous ganglia are intramedullary, non-neoplastic, subchondral cystic lesions containing mucoid fluid. Surgical treatment of this pathologic condition yields good results and a low recurrence rate. A 10 cm skin incision is made at the posterior glenohumeral joint. Biodegradable implants lead to problems such as cyst formation, soft-tissue inflammation, loose implant fragments or local osteolysis. In the absence of nerve compression symptoms it is a tad difficult to zero in on the diagnosis unless there is an image that supports the diagnosis. Curettage is a useful treatment option for a ganglion inside bone and very close to the suprascapular nerve. Tam W, Resnick D, Haghighi P, Vaughan L: Intraosseous ganglion of the patella. Biodegradable implants lead to problems such as cyst formation, soft-tissue inflammation, loose implant fragments or local osteolysis. Intraosseous ganglion (IOG) cysts of the humerus is a rare and often painful condition.5–9 There is only one other case in the literature describing an IOG cyst of the humerus, while most papers describe cystic lesions of the carpal and tarsal bones.6,10,11 Symptomatic IOG cysts present with intermittent pain, occasional swelling and it Some people have more than one lipoma.A lipoma isn't cancer and usually is harmless. Clinical presentation Patients may have mild localized pain. There was no communication between the cyst and the joint space. This report describes a case of an intraosseous ganglion of the proximal humerus. Posterior approach was used for operation incision. Intraosseous foreign body granuloma in rotator cuff repair with bioabsorbable suture anchor. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. An intraosseous ganglion is a benign bone lesion but is considered a neoplasm, which is similar to a ganglion occurring in soft tissue [3, 4]. However, only 11 cases of intraosseous ganglia of the glenoid have been reported. @article{Yi2009IntraosseousGO, title={Intraosseous ganglion of the glenoid causing suprascapular nerve entrapment syndrome: a case report. Other locations include the finger, palm of hand, wrist, elbow, shoulder, hip, knee, ankle and foot (Fig. The main complications are joint stiffness and vascular disturbances of the lunate bone. Mean average age of patients is 42 years. The cysts were curetted and filled with artificial bone (β-TCP). Wrist arthroscopy is a surgical technique that reduces the intra-articular operative area and therefore minimizes postoperative stiffness. 1). This study was approved by the Human Ethics Committee of Gifu University (no. It requires an MRI or MR Arthrogram to find out if it is as a consequence of a paralabral cyst. Thus, the intraosseous cyst was considered to be an intraosseous ganglion. A 48-year-old female patient presented with pain in her right shoulder. It mainly occurs in middle-aged people, and the most common site is the lower end of the tibia [4, 5]. The cyst of the shoulder girdle in most cases is diagnosed as an aneurysmal, solitary cysts in this zone are formed only in 20-25% of patients. GROSS PATHOLOGY. Based on these findings, it was considered that the intraosseous cyst in the glenoid compressed the suprascapular nerve at the spinoglenoid notch and induced the posterior shoulder pain, though a nerve conduction study for suprascapular nerve was not performed. Her symptoms did not improve after non-operative treatment. Plain anteroposterior radiography of the left shoulder showed a circular lesion with marginal osteosclerosis at the glenoid (Figure 1(b)). This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The suprascapular nerve was retracted gently, and curettage was performed until the bone surrounding the cyst was completely exposed (Figure 3(d)). Ganglion cyst in shoulder is not common, but when present can produce discomforting pain and weakness in shoulder. Abstract. 24) is an intraosseous cyst which occurs beneath an articular surface of a bone. Surgical treatment of this pathologic condition yields good results and a low recurrence rate.2 It consists of curettage of the cyst associated with a bone graft, mostly autologous graft, performed by an open surgical approach. Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. Usually ganglion cysts do not require to be treated if they do not produce any symptoms. Intraosseous ganglia of the glenoid are rare, and their etiology is unknown. The cysts were … Subchondral cysts are of variable size from a f… Computed tomography (CT) showed a circular cystic lesion with marginal osteosclerosis and cortical bone destruction of the posterior glenoid at the spinoglenoid notch (Figures 2(c) and 2(d)). Intraosseous ganglion of the glenoid causing suprascapular nerve entrapment syndrome: a case report. Nusselt T(1), Freche S, Klinger HM, Baums MH. The sac is usually primarily filled with hyaluronic acid. Intraosseous ganglion cyst is benign bony cyst that mainly involves epiphysis and metaphysis of long bones. Things to Do Immediately, How Long do Growing Pains Last? Based on the findings of MRI and CT, an intraosseous ganglion, cyst of degenerative disease, giant cell tumor, aneurysmal bone cyst, and chondroblastoma of the glenoid were suspected. We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. Here, we present a case of suprascapular nerve entrapment caused by an intraosseous ganglion in the glenoid, which was treated with curettage of the ganglion. May extend through the cortex into the joint, esp. A subchondral cyst is an intraosseous epiphyseal synovial fluid-filled void prevalent in osteoarthritis that may attain a diameter of 1-15 mm or more in size with the cyst’s longest axis usually along the coronal plane in the craniocaudal axis. About 2-4% of the general population is likely to have it and presentation may be common in males (especially around the third to fourth decade… (b) Radiograph of the left shoulder shows a radiolucent cystic lesion in the superior glenoid. Second, needle aspiration or incision under arthroscopy was speculated to be arduous because the main part of the ganglion was located inside the glenoid and it was apart from the glenohumeral joint cavity. However, if the cyst is inside the shoulder joint certain tests such as ultrasound, MRI, may be required for its diagnosis. 2019; 2(2):133. posterior to the anterior horn of medial meniscus (Figure 4) . Small intraosseous cysts (yellow arrowheads) typically form at the anterior margin of the femoral attachment of the ACL and at the posterior margin of the distal attachment. Therefore, we concluded that the protrusion of an intraosseous cyst of the glenoid into the spinoglenoid notch was a cause of the pain, and performed curettage. First you have to confirm it simple bone cyst or not. Clinical presentation Patients may have mild localized pain. On magnetic resonance imaging a cystic lesion of the proximal humerus was detected. Intraosseous ganglia are benign cystic and often multiloculated lesions located in the subchondral bone. After releasing the nerve gently from the cyst (Figure 3(c)), an incision was made at the cyst wall, and gelatinous material flowed out from the cyst.
