目的：探讨肝脏囊性恶性肿瘤的ＣＴ诊断价值。材料与方法：经手术病理和临床证实的肝脏囊性恶性肿瘤２９例，术前均行ＣＴ检查，其中转移瘤１５例，肝细胞性肝癌４例，肝肉瘤２例，囊腺癌４例（包括囊腺癌肉瘤１例），胆管癌３例和Ｃａｒｏｌｉ病癌变１例。结果：囊性转移瘤远较其他肝囊性恶性肿瘤常见，表现多样化，以多发囊性或囊性实质性病灶共存为其特点，小病灶亦可完全囊变；囊性肝癌表现为单发不均或均匀厚壁型肿块；囊性肝肉瘤为单房或多房囊性肿瘤；囊腺癌或囊腺癌肉瘤则为多房囊样病变或以囊性病变为主的囊实性肿块，有壁结节，周围可有卫星灶及远端胆管扩张；囊性胆管癌为囊实性病变，囊性部分呈较小多发囊性病灶，伴病灶远端胆管明显扩张；Ｃａｒｏｌｉ病癌变在Ｃａｒｏｌｉ病基础上部分扩张胆管癌变（胆管壁软组织肿块）。结论：肝脏囊性恶性肿瘤以转移瘤最常见，各种病理类型的囊性肿瘤有其相似和不同的ＣＴ征象，典型的ＣＴ特征结合临床，大部分肿瘤术前可作出正确诊断。
Objective: To investigate the diagnostic value of CT in diagnosis of cystic liver cancer. MATERIALS AND METHODS: Twenty-nine patients with malignant cystic liver tumors confirmed by pathology and clinicopathology were examined by CT before operation. There were 15 cases of metastases, 4 cases of hepatocellular carcinoma, 2 cases of hepatic sarcoma, 4 cases of cystadenocarcinoma Including 1 case of cystadenocarcinoma), 3 cases of cholangiocarcinoma and 1 case of Caroli’s disease. Results: Cystic metastases are much more common than other hepatic cystic malignancies. They are characterized by multiple cystic or cystic lesions and small lesions can be completely cystic. Cystic hepatocellular carcinoma Uneven or uniform thick-walled mass; cystic liver sarcoma of single or multiple cystic tumors; cystadenocarcinoma or cystadenocarcinoma sarcoma is more than cystic lesions or cystic lesions cystic mass , There are wall nodules, there may be satellite lesions and distal bile duct dilatation; Cystic cholangiocarcinoma is cystic solid lesions, Cystic part of the lesser multiple cystic lesions, with the distal lesion bile duct obvious expansion; Caroli disease Caroli disease based on the expansion of part of the bile duct cancer (bile duct wall soft tissue mass). Conclusions: Cystic tumors of liver are most common in metastatic tumors. Cystic tumors of various pathological types have similar and different CT signs. Typical CT features combined with clinical and most of the tumors can be correctly diagnosed before surgery.
