A case of sensory ataxia as the presenting manifestation of neurosarcoidosis

Muscle Nerve. 2011 Jun;43(6):900-5. doi: 10.1002/mus.22045.


Sarcoidosis rarely selectively affects the cauda equina with characteristic motor and sensory impairments.Using imaging, we report a case of cauda equina polyradiculopathy presenting with progressive sensory ataxia without clinical or electrophysiological evidence of motor involvement. Neurosarcoidosis was diagnosed pathologically by proximal dorsal root biopsy after systemic investigations for inflammatory, infectious, and neoplastic etiologies were found to be negative. There was clinical and radiographic improvement with corticosteroids. In addition, we review previously reported cases of cauda equina sarcoidosis.
