Diagnoses: We diagnosed it as suprascapular nerve entrapment at the spinoglenoid notch caused by an intraosseous ganglion of the scapula. Materials and Methods . An extraosseous cyst was located over the posterior glenoid neck, which had capsules filled with a transparent gelatinous substance. An intraosseous ganglion of the humeral head is rare and its correlation with the cuff tear was unclear. The patient was a 61-year-old woman with a painful left shoulder with a limited range of motion. The subchondral cyst was virtually nonexistent; the Baker’s cyst had reduced significantly and was non-palpable. Her visual analog scale (VAS) for pain was reduced in half of the initial score. If the cyst is causing pain or interfering with joint movement, your doctor may recommend: Immobilization. On magnetic resonance imaging a cystic lesion of the proximal humerus was detected. Intraosseous ganglia about the shoulder are rare; to the best of our knowledge, only 13 cases of intraosseous ganglia of the glenoid have been reported in literature. 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. Postero-superior intraosseous cysts of the humeral head were detected in 73.3% of all javelin throwers in the dominant shoulder, but only in 13.3% in the nondominant shoulder (P = .008). They most often occur at the back of the wrist, followed by the front of the wrist. There was no significant difference in the occurrence of cysts between patients older or younger than age 40 or between genders, but rotator cuff tears were seen significantly more often in the older age group (p 0.01). Her symptoms did not improve after non-operative treatment. The etiology is unknown, but association with degenerative joint disease has been considered. Clinical features Ganglion cysts of bone most commonly affect the hip and medial malleolus, while the knee, wrist, shoulder, and … Patient concerns: We report a 61-year-old woman who had complained right shoulder pain that lasted over 3 years which was exacerbated by overhead activities. - "Intraosseous ganglion of the glenoid causing suprascapular nerve entrapment syndrome: a case report." Paralabral cysts are swellings that arise around the socket of the shoulder joint (glenoid). However, only 11 cases of intraosseous ganglia of the glenoid have been reported. Ganglion cysts are often painless, requiring no treatment. The only selection criterion was the description of an intramuscular cyst or ganglion. Lennard Funk, 2011. Intraosseous ganglion is a cystic lesion that contains gelatinous material, most often occurs in middle-aged patients, and is regarded as similar to soft-tissue ganglion. Rotator cuff tears were present in 36 patients, and 79% of all tears occurred in supraspinatus tendon. The histological examination of cystic mass was expressed as ganglion. Your doctor may suggest a watch-and-wait approach. An intraosseous ganglion cyst is identical to its far more common soft tissue counterpart that occurs around joints and tendons in the hand or foot. Intraosseous ganglion cysts are benign lesions located in the subchondral bone adjacent to the joint and are usually found in adults [1]. There was no communication between the cyst and the joint space. A 35-year-old woman reported having a painful right shoulder of 4 months' duration. Lorenz Büchler, Harish Hosalkar, Martin Weber, Arthroscopically Assisted Removal of Intraosseous Ganglion Cysts of the Distal Tibia, Clinical Orthopaedics and Related Research®, 10.1007/s11999-009-0771-4, 467, 11, (2925-2931), (2009). Background . Intraosseous ganglion cysts are rare causes of wrist pain. ... Intraosseous ganglion cyst in which fibrous wall is of variable thickness with myxoid change. please consult your Orthopedician he will examine and treat you accordingly. These cysts may represent a synovial cyst, ganglion cyst or pseudocyst. Patients who had prior shoulder surgery and patients with paralabral or acromioclavicular joint cysts were excluded. Paralabral Cysts. What are paralabral cysts? The cause is unknown. The total number of reports searched was 9,366. In both cases, the genesis of the intraosseous ganglion cyst may be related to a long-term impingment between the greater tuberosity of the humerus and the acromion. Intraosseous ganglia are rare lesions that can cause pain and leave patients susceptible to pathologic fracture. Paralabral cysts are swellings that develop around the socket of the shoulder joint. Most cysts (94%) demonstrated communication with the joint post-arthrogram. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. 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. The patient was a 47-year-old woman with a painful left shoulder with a limited range of motion. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. Occasionally pain or numbness may occur. They are benign lytic tu-mors, generally lobular, and frequently located on the subchondral part of the long bone’s epiphysis.1 They can sometimes be found on the carpal bones (lunate, Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. The person with paralabral cyst has an increased risk of having glenoid labral tears.
