[Compression of the superficial branch of the radial nerve by a synovial ganglion of the elbow (about one case and literature review)].

Compression of the radial nerve at the elbow is quite rare; entrapment of its superficial branch is exceptional. Extrinsic compression is the most frequent etiology. Magnetic resonance imaging plays a major role in the diagnosis, and early surgical excision or echoguided drainage - in case of synovial ganglion - allows a total recovery. The authors report the case of a compression of the superficial branch of radial nerve by an elbow synovial cyst treated by surgical resection.
