Hemorrhagic ascites due to congestive heart failure.

Ascites due to congestive heart failure (CHF) is characteristically serous in gross appearance. Although hemorrhage into ascites commonly indicates a malignant or inflammatory cause, cirrhosis of the liver is a well known cause of bloody ascites. We report a case of hemorrhagic ascites due to biventricular congestive heart failure in which workup for other causes was negative and hemorrhage cleared after 4 months. In as much as the mechanism of ascites is similar in both cirrhosis and CHF, we propose that a similar mechanism could cause bleeding into ascites in CHF.
