A Case of Pseudo-Anterior Interosseous Nerve Syndrome Originating from Brachial Plexus |
|
Abstract |
A 32 year-old male patient with inability to pinch together the thumb and index finger was referred for electrodiagnostic study after the surgical exploration of forearm and index finger. Four days before surgical exploration, he attempted to grab a TV remote control deep underneath a couch by reaching his right hand while lying on the floor in prone position. And then, weakness of right thumb and index finger on flexion were gradually developed. He underwent surgical exploration diagnosed as a partial rupture of the second flexor digitorum profundus (FDP) tendon, but the surgical findings were negative. Electrodiagnostic finding were median nerve lesion above elbow on 11 days of onset, then suggested total brachial pleuxopathy at the trunk level on 19 days. This is the first reported case, to our knowledge, of pseudoanterior interosseous nerve syndrome originating from brachial plexus. Traction lesion of brachial plexus can develop symptoms and signs mimicking anterior interosseous nerve syndrome. |
