Post-heatstroke parkinsonism and cerebellar dysfunction

Abstract

A case is presented of a 45-year-old woman who developed parkinsonism, cerebellar dysfunction, aphasia and flaccid paralysis secondary to heat stroke. Magnetic resonance imaging revealed irregular patchy areas of increased signal intensity in the white matter of both cerebral hemispheres and the left striatum, remaining unchanged over a follow-up period of two years. Cerebellar atrophy, while not seen on initial examination, was present on the follow-up study done one year later and became more marked after two years.
