Abstract
Cubital tunnel syndrome (CTS) of the elbow secondary to a ganglion cyst is uncommon, with an incidence of 4 – 10% reported in some studies. This case report describes the ultrasound (US) and intraoperative findings of CTS caused by a ganglion cyst. It highlights the diagnostic importance of US and how it can provide detailed information regarding the severity of CTS. This report aims to raise awareness of ganglion cysts as a possible differential in cases of ulnar nerve neuropathy and to emphasize their relevance in surgical planning and management.
