Ganglion cyst at the spinoglenoid notch.: A case report and literature review

Introduction. - Entrapment of the suprascapular nerve at the spinoglenoid notch due to a ganglion cyst is an uncommon event and remains a challenge for clinicians. Exegesis. - We describe the findings in a 35-year-old patient with nonspecific pain in the shoulder and in whom MR revealed a ganglion cyst in the spinoglenoid notch, confirmed surgically. Conclusion. - Entrapment of the suprascapular nerve at the spinoglenoid notch due to a ganglion cyst must be considered in the differential diagnosis of nonspecific shoulder pain. MR imaging and electromyography can reach a positive, topographic, and etiologic diagnosis of suprascapular neuropathy. (c) 2005 Elsevier SAS. Tons droits reserves.
