Heat-stroke-induced cerebellar atrophy: clinical course, CT and MRI findings.

We report the clinical course and CT and MRI findings in a case of heat-stroke-induced cerebellar atrophy. Although the cerebellar syndrome was severe concomitant with the onset of heat stroke, no abnormality was observed on brain CT in the first 2 weeks following the event. Cerebellar atrophy was first noted after 10 weeks on MRI; it was progressive during a 1-year follow-up.
