A Case of Ascites by Pseudomembranous Colitis, Initially Diagnosed Malignant Asites / 대한소화기내시경학회지

ABSTRACT

Pseudomembranous colitis (PMC) is mostly related with the antibiotics and it presents with diarrhea, abdominal pain, fever, hypoalbuminemia and hypovolemia. In the clinical course of pseudomembranous colitis (PMC), ascites is a rare presentation, and high elevation of carcinoembryonic antigen (CEA) associated with PMC is also a very rare presentation. We experienced a case taken cephalosporin group antibiotics for six weeks and presented with fever, abdominal pain, severe diarrhea, and massive ascites. During evaluation, we found low serum-ascites albumin gradient and high level of CEA in both ascites and plasma. With the impression of hidden malignancy, the special studies were done, but PMC was only found without malignancy. After vancomycin therapy, all symptoms were relieved and CEA level declined.
