Chronic colonic perforation in pseudomyxoma peritonei.Br J Radiol. 2007 May; 80(953):e94-7.BJ
Pseudomyxoma peritonei (PP) produces abundant mucoid material from the rupture of low grade ovarian or appendiceal mucinous tumours. The unique pattern of cancer dissemination and intraperitoneal mucous re-distribution makes it a distinct clinical condition. It has diverse presentations, mainly as a result of narrowing of the gastrointestinal tract and entrapment of other viscera by gelatinous mucoid material. Imaging is helpful, but not diagnostic of this condition. We report a patient with pseudomyxoma perotonei who had perforation at the recto-sigmoid junction into a large mucinous cyst adjacent to the sigmoid colon. The patient improved clinically with conservative management, with persisting communication and no adverse symptoms reported at 4 months follow-up.
