【摘要】 目的　分析腹内囊腺癌的CT表现并重点探讨其共同CT特征。资料与方法　搜集经手术病理证实的腹内囊腺癌 4 5例 ,其中来自肝、胰和卵巢分别为 4例、16例和 2 5例。所有病例均经CT平扫和增强扫描。结果　腹内囊腺癌的共同CT表现有 :大部分为多房囊性肿块 ,囊壁及分隔厚薄不均、毛糙并有不同程度强化 ,多有壁结节或肿块实质部分 ,少数伴有钙化。肿瘤复发与原发灶CT表现相似 ,胰、卵巢囊腺癌可出现囊样肝转移。结论　腹内囊腺癌具有多种相似CT特征 ,认识这些特征有助于对这类疾病的正确诊断。更多还原

【Abstract】 Objective To discuss CT findings and common characteristics of abdominal cystadenocarcinomas. Materials and Methods Forty-five cases with pathologically-proved abdominal cystadenocarcinomas were collected, which were originated from the liver (n=4), pancreas (n=16) or ovary (n=25). Both plain and enhanced CT scans were performed in all cases. CT findings were analyzed. Results The common findings included multiloculated cystic tumor (or mixing with solid mass), rough and uneven thickness of the cystic wall and septa with different enhancement, nodules on the cystic wall, solid mass and calcifications in some cases. Recurrence had similar manifestations to that of primary tumor. Cystadenocarcinoma of the pancreas and ovary could cause cystic hepatic metastasis. Conclusion Abdominal cystadenocarcinomas have many similar CT signs. A familiarity with these features is helpful for the diagnosis of the disease.更多还原
