title: Diagnosis of pseudomembranous colitis by computed tomography: a report of two patients.
abstract: In patients with pseudomembranous colitis, the colonic wall has a characteristic appearance on computed tomographic scans of the abdomen: it is diffusely thickened and the ascending or descending colon viewed on end has a donut-like appearance. It is important to recognize the possible association of such findings with pseudomembranous colitis in order to make an accurate diagnosis in patients experiencing an acute abdominal catastrophe.
