Case 127. Microsporidiosis (22 y-o M)

       
  Biopsied multifocal white matter lesions, up to 1 cm in size, seen in an HIV-negative patient who often eats raw cow liver  
       

 

  The basophilic short rods are focally clustered within a cytoplasmic vacuole in the other astrocyte (HE, oil immersion). Microsporidiosis, probably infection of Encephalitozoon sp., is strongly suspected.
