Discussion (Related Text)

Pseudomyxoma peritonei ("jelly belly") refers to gelatinous ascites that occurs as a result of intraperitoneal spread of mucin-producing cells resulting from rupture of appendiceal mucocele, intraperitoneal spread of benign or mucinous cysts of the ovary, or mucinous adenocarcinoma of the colon or rectum . Conventional radiographs may demonstrate punctate or ringlike calcifications scattered through the peritoneal cavity. CT demonstrates mottled densities, septations, and calcifications within the fluid. The mucinous fluid is typically loculated and causes mass effect on the liver and bowel . US demonstrates intraperitoneal nodules that range from hypoechoic to strongly echo genic.
