title: Hemorrhagic colitis caused by Escherichia coli O157:H7--unusual ultrasonographic and computed tomography findings.
abstract: Hemorrhagic colitis due to Escherichia coli O157:H7 occurs sporadically but widely throughout North America. Radiographically this condition may mimic ischemic colitis, inflammatory bowel disease, acute appendicitis or appendiceal abscess. Correlation of radiologic and clinical findings is required to ensure diagnostic accuracy and avoid unnecessary surgical intervention.
