Abstract

Wilson disease is an autosomal recessive disorder of abnormal copper metabolism. Peripheral neuropathy has rarely been reported in the context of Wilson disease, so we report a case of peripheral neuropathy in Wilson disease. A 31-year-old man visited us with complaints of paresthesia, tingling sensation and hypokinesia in both upper and lower limbs, which has begun about 5 years ago and worsened gradually. He was diagnosed as Wilson disease about 10 years ago, has taken medication irregularly and had no other remarkable underlying disease. On laboratory test, there were no remarkable abnormal findings, which could cause peripheral polyneuropathy. On electrophysiologic study, left tibial nerve response was of decreased velocity and bilateral sural, medial and lateral plantar nerve responses were not evoked, which findings were consistent with distal symmetric sensorimotor polyneuropathy.

Key Words: Wilson disease, Polyneuropathy
