Anterior Interosseous Nerve Syndrome with Varient Nerve Innervation: A Case Report

ABSTRACT

Anterior interosseous nerve syndrome is characterized by weakness of the flexor pollicis longus, the flexor digitorum profundus and the pronator quadratus in the presence of normal sensation. Although MR imaging findings of anterior interosseous nerve syndrome has been reported in a few articles, we report herein a case of anterior interosseous nerve syndrome involving more than usual muscles innervated by anterior interosseous nerve, caused by varient nerve innervation.
