Morvan's fibrillary chorea: remission after plasmapheresis

We evaluated the effects of plasmapheresis in two patients with Morvan's fibrillary chorea, one of whom had sigmoid carcinoma, with oligoclonal bands in the cerebrospinal fluid, and modifications of the lipid-oxidative muscle pattern. The use of plasmapheresis in the treatment of Morvan's fibrillary chorea has not been reported previously and in our patients improved the symptoms markedly.
