ABSTRACT

Clinical data and manifestations on muhi-slice spiral CT (MSCT) of 11 patients with disseminated peritoneal adenomucinosis (DPAM) were retrospectively reviewed.The CT manifestations were also compared with surgical and histopathological findings.MSCT findings showed a large amount of gel-like ascites in 9 cases and local cystic masses in 2 cases.Among 9 cases with a large amount ascites,abdominal multiple cystic masses were shown in 5 case,and infiltration of the greater omentum and mesentery in 5 cases.Hepatic scalloping was found in 6 cases ; parenchymal invasion of the liver or spleen were showed in 5 cases; calcification of the cystic masses in 5 cases.Ovary mueinous cystadenoma was presented in 3 female patients.Enlarged lymph nodes and omental cake were not found in all cases.The results indicate that the characteristic MSCT manifestations of DPAM include diffuse gel-like ascites,multiple cystic masses with or without calcification,hepatic scalloping and parenchyma invasion.
