摘要
目的比较分析肝硬化性血管瘤与肝海绵状血管瘤、肝细胞癌、肝胆管细胞癌及转移性肝癌的影像学表现差异,提高对该病的认识及术前诊断水平。方法收集并分析自2000～2008年上海东方肝胆外科医院经手术病理证实的10例肝硬化性血管瘤的临床影像学资料包括CT、MRI表现。结果本组肝硬化性血管瘤缺乏肝海绵状血管瘤的典型CT及MRI特征:CT增强动态扫描显示肿瘤动脉期、门脉期均无明显强化,延时扫描病灶强化较为明显;MRIT1加权像病灶为低信号,T2加权像病灶表现为由多种信号组成,部分病灶呈高信号。其中3例误诊为肝细胞癌,2例误诊为胆管细胞癌,1例误诊为胆管细胞癌合并感染,1例误诊为肝转移瘤,1例误诊为肝脓肿,1例误诊为非典型性海绵状血管瘤,1例误诊为后腹膜肿瘤。结论认识肝硬化性血管瘤的影像学表现,对于提高该病的认识和术前诊断水平,避免不必要的手术具有重要意义。
Objective To study the differences between sclerosing haemangioma and carvernous hamangioma of liver.hepatocellular carcinoma.Hepato-Cholangio-Careinoma and hepatic matastasis cancer to improve the level of recognition and preoperative diagnosis of this disease. Methods Between 2000 and March 2008,the clinical and radiologieal datus（ineluding CT and MRI images） of 10 patients of EHBH were analyzed, which were confirmed by pathology after surgical resections. Results This group of clerosing haemangioma of liver are lack of typical CT and MRI image characteristics of carvernous hamangioma of liver： dynamic enhanced CT scanning shows that there is no apparent enhancement of the tumor on the arterial phase and portal phase, but apparent enhancement of the tumor on equilibrium phase;MRI shows that hypointense on T1 WI of the lesion, multi-intense on T2WI,of which part of lesion is hyperintense. Among these 10 cases,3 cases were misdiagnosed of heptoeellular carcinoma,2 cases were misdiagnosed of Hepato-Cholan- gio-Careinoma, one were misdiagnosed of Hepato-Cholangio-Carcinoma combined with infection, one were misdiagnosed of hepatic matastasis cancer, one were misdiagnosed of abscess of the liver, one were misdiagnosed of atypical carvernous hamangioma of liver, one were misdiagnosed of Retroperitoneal tumor. Conclusion Being familiar with the radiological characteristics of selerosing haemangioma of the liver provide us great importance for improving the level of recognition and preoperative diagnosis of this disease and avoiding inappropriate operations.
