Multifocal sensory demyelinating neuropathy: Report of a case

Introduction: Multifocal sensory demyelinating neuropathy has not been adequately reported in the literature. Methods: A 42‐year‐old man with numbness of the left hand for 3 years and of the right hand for 6 months had a pure multifocal sensory neuropathy involving both hands, most prominently affecting 2‐point discrimination, number writing, and object recognition of the left hand. Near‐nerve needle sensory and mixed nerve conduction studies were performed on the left ulnar nerve. Results: Studies of the left ulnar nerve documented a demyelinating neuropathy characterized by temporal dispersion and marked decrease in the amplitudes of the sensory and mixed compound nerve potentials in the above‐elbow‐axilla segment. With intravenous immunoglobulin treatment, there was improvement in his neuropathic condition. Conclusion: In this study I describe a case of multifocal sensory demyelinating neuropathy as a counterpart of multifocal motor neuropathy. Muscle Nerve 56: 825–828, 2017
