Is nerve biopsy useful in diagnosis of CIDP?

Abstract

Chronic inflammatory demyelinating polyradiculopathy is mainly based on clinical and electrophysiological criteria. If electrophysiological findings remain questionable for the diagnosis of CIDP and/or clinical presentation is atypical, nerve biopsy may assist the diagnosis. We present a case in which the nerve biopsy was helpful in diagnosis of CIDP and revealed the peculiar presence of tomacula.
