OBJECTIVETo study the characteristics of computed tomography (CT) appearance in pseudomyxoma peritonei.

METHODSCT findings were retrospectively reviewed in 7 patients with surgically and pathologically confirmed pseudomyxoma peritonei.

RESULTSAll patients had large-volume ascites with heterogeneous density, hepatic and splenic scallopings, and peritoneal and omental infiltration on CT. Omental cakes in 3 patients and appendiceal masses in 2 patients were found. Other findings included calcification, septa, mucinous masses, pleural effusion, and ureteral dilation.

CONCLUSIONCT appearance in pseudomyxoma peritonei has certain characteristics, which should be carefully recognized by radiologists during examinations.
