Imaging Features of Enterohemorrhagic Escherichia coli Colitis

The purpose of this article is to define and illustrate the radiologic findings in patients with enterohemorrhagic Escherichia coli colitis. Although not definitive, imaging studies in conjunction with an appropriate clinical history can aid in the early diagnosis of E. coli colitis and exclude surgical conditions. CT is more sensitive than conventional radiography for detection. Contiguous involvement, including the transverse colon, was seen in all patients. Because CT is becoming routine in the initial workup of patients with acute abdominal pain, it is important for the radiologist to suggest E. coli colitis in the proper setting.
