Compression of the Radial Nerve Caused by an Occult Ganglion

Abstract

We report on three patients with radial nerve compression in the region of the supinator muscle caused by an occult ganglion. After excision of the ganglion and decompression of the posterior interosseous nerve, the nerve palsy resolved completely in all cases.

Radial Palsy Caused by Ganglion of the Elbow

“…(a) Injuries of the elbow, such as shot and stab wounds, circular saw injuries, Monteggia-like fractures, and chronic injuries caused by repeated pro-supination [1-5] (b) Tumors between the two planes of the fibers of the supinator-lipoma, fibroma, schwannoma, bicipital bursitis, or a ganglion [6][7][8][9][10][11][12][13][14][15][16][17] (c) Inflammation in the elbow, especially bursitis bicipitoradialis [18,19] The anatomy of the radial nerve in the elbow can be described as follows. After leaving the upper arm between M. brachialis and M. brachioradialis, the nerve shows some variation in the level at which the sensory superficial branch deviates from the main trunk.…”

A ganglion cyst at the elbow causing superficial radial nerve compression: a case report

“…Most previously reported cases of radial nerve compression have been located just anterior to the radial head, proximal to the arcade of Frohse [ 2 ]. Yamazaki reported 14 patients presenting with incomplete paralysis of the extensors of the wrist and fingers due to a ganglion at the elbow, located proximal to the arcade of Frohse in 13 cases and distal in 1, all causing PIN palsy [ 3 ].…”

Delayed diagnosed posterior interosseous nerve palsy due to intramuscular myxoma

“…Soft tissue tumours such as lipomas,8 rheumatoid synovitis,9 synovial chondromatosis,10 neurofibromas,11 haemangiomas,12 intracapsular chondroma13 or tumour-like masses such as ganglions,14 bursitis15 or even pseudogout16 can cause PIN palsy.…”
