Although pseudomembranous colitis is a well established pathological entity, the precise pathogenesis is still uncertain. Recently, an increasing number of patients have been described with antibiotic-associated pseudomembranous colitis. Four patients with pseudomembranous colitis related to antibiotic therapy had a wide spectrum of radiographic features. These ranged from mild, focal areas of mucosal irregularity to widespread involvement of the colon. The extensive mucosal irregularity at Ba enema is caused by plaque-like elevated pseudomembranes studding the mucosal surface and appears to be a specific radiographic finding. Dissection of Ba under the pseudo-membranes and intramural gas were observed in these patients. Case 2 had a complicated, massive colonic bleeding, unresponsive to pitressin infusion.
