Neuralgic amyotrophy with bilateral diaphragmatic palsy.

Abstract

Neuralgic amyotrophy is a well recognised condition of unknown aetiology with characteristic clinical features.' These include severe pain in the shoulder region, followed within hours or weeks by motor or sensory abnormalities, or both, in the distribution of the cervical roots or nerves. Unilateral disease is more common clinically but if elec- tromyographic (EMG) studies are performed bilateral dis- ease is often found.2
