摘　　要：目的探讨阑尾黏液性囊腺癌的CT表现特征。方法回顾性分析5例经手术及病理证实的阑尾黏液性囊腺癌的CT资料，并复习相关文献。结果5例均表现为右下腹囊性肿块，4例呈不规则分叶状，1例管状。最大横径约27～146mm，局部侵犯邻近肠管而边界欠清晰。囊壁厚薄不均匀，内壁欠规则并见小结节或乳头状突起；3例囊内见纤维分隔。囊内可见较多黏液，密度欠均匀，平均CT值约19．3～34．6HU。增强显示囊壁及分隔较明显强化4例，中等强化1例。3例肿瘤边缘脂肪间隙较清晰，2例合并急性炎症导致邻近脂肪间隙较模糊。3例囊壁见细微点状钙化，3例邻近淋巴结肿大。结论CT可以显示阑尾黏液性腺癌的一些病理特征，对其诊断及鉴别有较大价值。Objective To explore the CT characteristics of mucinous cystadenocarcinoma of appendix. Methods The CT findings of 5 patients with mucinous cystadenocarcinoma of appendix proved by surgery and pathology were analyzed retrospectively,and the corresponding literatures were also reviewed. Results All lesions in 5 patients showed cystic changes in the right hypogastrium inclu ding irregular shape with lobulation in 4 and tubular shape in 1. The maximum traverse diameters ranged from 27 mm to 146 mm. Unclear boundary was showed if the lesion invaded the adjacent gut. The cystic wall was asymmetry and thickened with little nodes and nipple in the inner wall. The thick septa were seen in 3 tumors. Much mucus was seen in tumors with uneven density and average CT value of 19.3 HU-34.6 HU. On enhanced CT,obvious enhancement of the cystic wall and septa in 4 and moderate enhancement in 1 was showed. The adjacent fatty gap of 3 tumors were clear,however it was vague when accompanied with acute inflammation. Small calcification in 3 and enlarged lymphatic nodes in 3 were also found. Conclusion CT shows some characteristics of mucinous cystadenocarcinoma of appendix and plays an important role in the diagnosis of the disease.
