The extraosseous cyst extended to the intraosseous lesion directly. Consequently, the shoulder pain was resolved promptly without suprascapular nerve complications, and the cyst was histologically diagnosed as an intraosseous ganglion. The cysts were curetted and filled with artificial bone (β-TCP). Diagnoses: We diagnosed it as suprascapular nerve entrapment at the spinoglenoid notch caused by an intraosseous ganglion of the scapula. Wrist arthroscopy is a surgical technique that reduces the intra-articular operative area and therefore minimizes postoperative stiffness. Intraosseous ganglion cysts are rare causes of wrist pain. Recently, a simple and safe less invasive arthroscopic approach was reported for patients with spinoglenoid ganglion cysts [11]. 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]. Complications may include carpal tunnel syndrome.. Intervention and outcome: A trial of passive care was conducted, including soft tissue therapy, spinal 1, 2 The pathogenesis of intraosseous ganglion cysts remains unclear, and these cysts fall into 2 categories: the primarily intraosseous “idiopathic” type and the penetrating type.

This case demonstrated that the intraosseous ganglion of the glenoid was a benign lesion but could be a cause of suprascapular nerve entrapment syndrome. On magnetic resonance imaging a cystic lesion of the proximal humerus was detected. An intraosseous ganglion of the humeral head is rare and its correlation with the cuff tear was unclear. 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. This report describes a case of an intraosseous ganglion of the proximal humerus. We describe a case of suprascapular nerve entrapment caused by protrusion of an intraosseous ganglion of the glenoid into the spinoglenoid notch. B, Axial view. 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 cause is unknown.

Direct communication between a cyst and joint is not commonly seen. An extraosseous cyst was located over the posterior glenoid neck, which had capsules filled with a transparent gelatinous substance.
