Suprascapular nerve entrapment at the spinoglenoid notch caused by a ganglion cyst.
A 34-year-old man had right infraspinatus muscle palsy and posterior aching of the shoulder caused by electromyographically confirmed suprascapular nerve entrapment. Sonography and magnetic resonance imaging revealed a cystic lesion at the spinoglenoid notch; this lesion was diagnosed as a ganglion. Operative removal led to immediate pain relief and incomplete recovery of the compressed branches of the suprascapular nerve.
