Wilson Disease With an Initial Manifestation of Polyneuropathy

Abstract

BACKGROUND: Recognition of Wilson disease (WD) is sometimes difficult because of its diverse manifestations. Peripheral neuropathy is rarely reported in the context of WD. OBJECTIVE: To report an unusual patient with WD whose initial manifestation was peripheral neuropathy. DESIGN: Case report. SETTING: Neurology department in a tertiary referral center. METHOD: Personal observation. RESULT: A 17-year-old man, who was eventually diagnosed with WD, was initially seen with polyneuropathy at least 6 months prior to developing more typical symptoms of WD. Electrophysiological and pathological studies suggested a neuropathy of mixed type. Treatment for WD resulted in clinical and electrophysiological improvement. CONCLUSION: Wilson disease may initially appear as a treatable polyneuropathy.
