Acute and chronic polyradiculopathies.

Autor(es): Rubin Devon I

Resumo: Polyradiculopathies are uncommon peripheral nervous system syndromes that result from a variety of conditions. The clinical manifestations are variable but often include symmetric or asymmetric distal and proximal weakness with a variable degree of sensory loss and reduction or loss of reflexes. The most common cause of an acute polyradiculopathy is acute inflammatory demyelinating polyradiculopathy (also known as Guillain-Barré syndrome); however, other inflammatory, infectious, or neoplastic causes can present with similar features. Chronic polyradiculopathies include chronic inflammatory demyelinating polyradiculopathy as well as paraprotein-related syndromes and other inflammatory and infectious causes. Evaluation using a combination of serologic studies, electrodiagnostic testing, and CSF evaluation can help to identify the underlying etiology and implement the appropriate treatment. This article reviews the approach to patients with suspected polyradiculopathy and the features of the more common causes of acute and chronic polyradiculopathies.
