Abstract

We report an extremely rare case of proximal entrapment neuropathy of the median nerve above the elbow in a 44-year-old man who presented with paresthesia with median nerve distribution. Tinel's sign was located in the upper arm medial to the biceps and 5 cm proximal to the elbow. The patient underwent microsurgery under local anesthesia. The fascia covering the brachial- and the biceps brachii muscle entrapped median nerve. After operation, he reported symptom improvement. Lesions above the elbow should be considered as possible causative factors of entrapment neuropathy of the median nerve.
