Calcification of pseudomyxoma peritonei following intraperitoneal chemotherapy: CT demonstration.

Pseudomyxoma peritonei is essentially mucinous ascites, resulting from the intraperitoneal rupture of a malignant mucinous lesion with seeding of peritoneal surfaces. We report a case of pseudomyxoma peritonei from a perforated mucinous adenocarcinoma of the appendix in which radiographically demonstrable punctate calcifications developed during the course of intraperitoneal chemotherapy.
