BRACHIAL NEURITIS PRESENTING AS ANTERIOR INTEROSSEOUS NERVE COMPRESSION - IMPLICATIONS FOR DIAGNOSIS AND TREATMENT - A CASE-REPORT

Brachial plexus neuropathy may present as an isolated peripheral nerve lesion, suggesting local compression, when in fact the pathophysiolog y is a diffuse proximal inflammation. The type of management depends o n an accurate diagnosis of the diffuse lesion with electromyography. A descriptive case of isolated anterior interosseus nerve palsy is pres ented and the literature is reviewed. Analysis of the reported cases r eveals that anterior interosseus nerve palsies resulting from differen t etiologies are included in the same series and that treatment recomm endations are highly specialty-oriented. Cases of brachial plexus neur itis-induced anterior interosseus nerve palsy should be managed conser vatively, while surgical decompression may be performed for specific i nstances of direct trauma.
