MNGIE neuropathy: five cases mimicking chronic inflammatory demyelinating polyneuropathy.
We report five patients with mitochondrial neurogastrointestinal encephalomyopathy (MNGIE) who had demyelinating peripheral neuropathy. The MNGIE neuropathy had clinical and electrodiagnostic features typical of acquired, rather than inherited, etiologies. In fact, three patients were actually treated for chronic inflammatory demyelinating polyneuropathy (CIDP). We discuss findings that may help distinguish patients with MNGIE from those with CIDP.
