肝胆管囊腺癌的CT表现--附5例报告

目的探讨肝胆管囊腺癌的CT表现,评价CT对其诊断价值。方法回顾性分析我院2000年1月～2005年8月经手术病理证实的5例肝胆管囊腺癌的临床及CT资料。5例均作螺旋CT平扫及三期增强扫描。结果5例均为女性,年龄58～76岁,病灶位于肝左叶3例,右叶1例,左右叶同时受累1例。均为多发囊性病灶,有厚薄不均的囊壁和分隔;其中3例有壁结节和(或)乳头状突起,1例病灶中有实质性软组织肿块,1例有囊内出血。CT均见囊内主要为水样密度,增强后CT均表现为囊壁、分隔及囊腔内实质部分有强化。结论CT可显示肝胆管囊腺癌的特征性表现,如见病灶有增厚囊壁和分隔、有壁结节和(或)乳头状突起、囊内出血多考虑为肝胆管囊腺癌。因此CT是诊断肝胆管囊腺癌重要、可靠的方法。

CT finding of billiary cystadenocarcinoma: 5 cases report

Objective To summarize the CT features of billiary cystadenocarcinoma, and to evaluate the value of diagnosis with CT. Methods The clinical data and CT manifestation of five patients with billiary cystadenocarcinoma confirmed by pathology were analyzed retrospectively. Plain scan and three phase enhanced scan were performed in all cases. Results The five patients were female with the age of 58-76. The tumor were located in the left in three cases, right in one, and both side in one. The five patients suffered from billiary cystadenocarcinoma with multilocular cyst, thick or thin cyst wall and internal septation. All five cases were revealed as cystic mass in CT scan. Three cases had mural nodules and /or papillary excrescences, one had excrescences in the cystic lesions, one had bleeding in the cyst. After intravenous contrast injection, the cyst wall, septations and masses were enhanced in CT scan. Conclusion CT can show the characteristics of billiary cystadenocarcinoma, such as irregular thickening of internal septa, mural nodules, papillary excrescences, bleeding in the cyst. CT is very important and reliable in diagnosis of biUiary cystadenocarcinoma.
