A Rare Cause of Shoulder Pain: Ganglion Cyst of the Acromioclavicular Joint

Abstract

Ganglion cysts generally form after repeated microtrauma to the dorsum of the wrist. They are gel-filled cystic formations that may be rooted in the joint capsule, tendon, or tendon sheath. Ganglion cysts rooted in the shoulder and acromioclavicular joint are rare. We report a patient who presented with pain in the right shoulder, who was diagnosed with atypical localization of a ganglion cyst after clinical and radiological investigation. Post-operatively, histopathology confirmed the diagnosis. The case is presented along with the surgical results.
