Abstract
A 50-year-old woman presented with bloody diarrhea and radiological evidence of right sided colitis. Enterohemorrhagic Escherichia coli was isolated from the stool. The illness subsided spontaneously but was complicated by the development of hypoproteinemia and ascites. This disease presents a variable clinical picture but apparent 'ischemic colitis' in younger patients is especially suggestive of infection with E coli 0157:H7.
