SARCOIDOSIS OF THE PERIPHERAL NERVOUS-SYSTEM

The clinical and electrophysiologic data of four new patients with sar coidosis involving the peripheral nerves are presented and the subject is reviewed. Two had a symmetric polyneuropathy and two had polyradic ulopathy. These plus the few cases in the literature indicate that the findings on electromyography are most consistent with axonal neuropat hy, in a multifocal pattern. Needle electrolyography was more useful t han nerve conduction studies in identifying lesions.
