Case Of the Week (COW) 13 Oct 2013
Answer:
PSEUDOMYXOMA PERITONEI, POST RIGHT HEMICOLECTOMY FOR ADENO CARCINOMA OF ASCENDING COLON
FINDINGS: TOPOGRAM: Ascending colon and part of the transverse colon is not opacified – consistent with post right hemicolectomy for adenocarcinoma of ascending colon. CECT: Multiple low attenuation poorly enhancing peritoneal implants causing scalloping of liver and splenic surface. Ascites. Multiple Cystic and Solid peritoneal implants. One of the implant in RIF region causing Right mild obstructive hydro uretero nephrosis ( Not shown ).
DISCUSSION: Pseudomyxoma peritonei is a specific type of peritoneal neoplasia due to rupture of a mucinous cystadenocarcinoma or cystadenoma of ovary or appendix. Imaging findings include masses of low attenuation on CT and moderately high signal intensity on MRI accompanied by ascites, with septations representing the margins of mucinous nodules ,, and soft-tissue thickening of the peritoneal surfaces ,reflecting the more solid components of the tumour. Scalloping of the liver and spleenic edge by adjacent mucinous peritoneal implants is characterestics of pseudomyxoma peritonei.
