播散性腹膜黏液腺病多层螺旋CT诊断分析

Characteristic manifestations of disseminated peritoneal adenomucinosis on multislice spiral CT

回顾性分析11例播散性腹膜黏液腺病患者的CT资料，11例患者中有9例显示为弥漫性凝胶状腹水，2例显示为局限性囊性肿块。9例弥漫性病例中5例伴腹腔多发囊性结节或肿块影，5例伴大网膜或肠系膜网状浸润。11例患者中6例出现肝脏或脾脏扇形压迹，5例出现肝脏或脾脏实质浸润，5例于囊性结节或肿块内出现弧线状、结节状钙化。6例女性患者中3例有卵巢黏液性囊腺瘤。所有病例均未见腹腔及腹膜后淋巴结肿大，未见网膜饼征象。提示播散性腹膜黏液腺病具备特征性CT征象。

Clinical data and manifestations on multi-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 muhiple 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 mucinous eystadenoma 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.
