A patient with acquired immunodeficiency syndrome and untreated Encephalitozoon (Septata) intestinalis microsporidiosis leading to small bowel perforation. Response to albendazole.

Abstract

Encephalitozoon intestinalis symptomatically targets many organs, including the urinary bladder. To our knowledge, this is the first tissue-documented case of cystitis. Left untreated with albendazole, small bowel infection can lead to perforation and peritonitis.
