Diagnostic utility of somatosensory evoked potentials in chronic polyradiculopathy without electrodiagnostic signs of XXXX .

INTRODUCTION: Diagnosis of @entity2646 ( @entity2646 ) remains uncertain when nerve conduction studies (NCS) fail to show @entity17 . METHODS: We conducted a retrospective study of @entity1 who presented with clinical criteria of @entity2646 in whom electrodiagnostic (EDX) criteria of definite or probable @entity2646 were missing [axonal sensory-motor @entity16 (n=23), normal EDX with pure sensory presentation (n=3)]. All @entity1 received immunomodulatory treatment. Twenty-six @entity1 were evaluated with somatosensory evoked potentials (SSEPs), MRI of spinal roots, CSF analysis, and/or nerve biopsy. Diagnosis of @entity2646 was considered to be confirmed in @entity1 who responded to immunotherapy. RESULTS: 22 of 26 @entity1 (85%) had SSEPs reflecting abnormal proximal conduction in sensory fibers, including 14 who had only clinical and SSEP data in favor of @entity2646 . SSEPs were abnormal in 16 of 20 responders (80%) to immunotherapy. CONCLUSION: SSEP recording contributes to diagnosis of @entity2646 when NCS fail to detect @entity8954 .
