Acute cerebellitis is postulated to result from viral and/or autoimmune eti
ologies. This disease has been reported to have a variable course. We repor
t a case of sudden death from acute fulminant cerebellitis in a 13-year-old
ballet dancer. Serial CT and MRI demonstrated rapid progression of the dis
ease. Histopathologic correlation is provided. The etiologies, clinical cou
rse, therapeutic interventions and postmortem evaluation of this potentiall
y life-threatening condition are briefly reviewed. Copyright (C) 2001 S. Ka
