title: Significance of multimodality evoked potential abnormalities in sarcoidosis.
abstract: To assess central nervous system (CNS) involvement with normal CNS examination, multimodality evoked potentials were obtained in 25 patients with confirmed multisystem sarcoidosis. Twelve patients had abnormal evoked potentials: brainstem auditory evoked potentials (BAEP) were abnormal in 5, median nerve somatosensory evoked potentials (SEP) were abnormal in 4, and visual evoked potentials (VEP) were abnormal in 6 patients. Contrast-enhanced magnetic resonance imaging (MRI) of the brain in two patients with abnormal evoked potentials revealed no supportive structural lesions. Multimodality evoked potentials can detect subclinical neurosarcoidosis and are an important adjunct to neuroradiology in the diagnosis of neurosarcoidosis.
