Computed tomography appearance of pseudomyxoma peritonei

Objective: To study the characteristics of computed tomography (CT) appearance in pseudomyxoma peritonei.

Methods: CT findings were retrospectively reviewed in 7 patients with surgically and pathologically confirmed pseudomyxoma peritonei.

Results: All 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.

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