Castlemanʹs disease associated with chronic inflammatory demyelinating polyradiculoneuropathy: a clinical and electrophysiological follow-up study

Castlemanʹs disease (CD), or angiofolicullar lymph node hyperplasia, is a rare lymphoproliferative disorder that can be associated with peripheral neuropathy. We report the long-term follow-up of a patient with a chronic inflammatory demyelinating polyradiculoneuropathy complicating the mediastinal form of classic CD who improved notably with immunosuppresive therapy. Our findings suggest that serial electrophysiological studies may be useful for monitoring treatment efficacy.
