Abstract

Objective

To describe peripheral neuropathy associated with familial Creutzfeldt-Jakob disease.

Methods

We report two unrelated patients with genetic Creutzfeldt–Jakob disease with demyelinating peripheral neuropathy as initial presentation, with a comprehensive clinical, electrophysiological and neuropathological description.

Results

Both patients exhibited gait disturbance and paresthesia. Electrodiagnostic studies revealed demyelinating abnormalities with motor conduction blocks suggestive of chronic inflammatory demyelinating polyradiculoneuropathy, with abnormal plexus MRI and elevated CSF protein levels. One of them had pes cavus and a late-onset Charcot–Marie-Tooth (CMT) disease was also initially hypothesized. Central nervous system involvement manifested 1–2 years after the onset of peripheral symptoms. Both patients had a heterozygous E200K mutation in the PRNP gene. Postmortem neuropathological examinations showed PrPSc deposits in the peripheral nervous system, particularly in Schwann cells. Interpretation: Peripheral neuropathy in E200K genetic forms of Creutzfeldt-Jakob disease can be inaugural and mimic chronic inflammatory demyelinating polyradiculoneuropathy.
