目的探讨原发性肝脏透明细胞癌(primary clear cell carcinoma of the liver,PCCCL)的多层螺旋CT(MSCT)表现。资料与方法回顾性分析经手术病理证实的8例PCCCL患者的临床及MSCT资料。结果 8例均有乙肝病史,其中男性患者7例,甲胎蛋白(AFP)阴性6例。8例均为单发病灶,6枚病灶发生于肝右叶,多呈圆形、椭圆形或浅分叶,无包膜,边界不清,以实性成分为主,瘤内可见坏死区。CT平扫示肿瘤实性部分呈低密度或等密度。CT双期增强扫描,5枚病灶呈轻度强化,以病灶的边缘区强化明显,1枚病灶呈斑片状不均匀强化;2枚病灶呈典型普通型肝细胞癌的“速升速降”强化方式;1枚病灶呈明显强化,门静脉期强化程度高于动脉期;病灶中心的坏死区均不强化。结论 PCCCLMSCT影像学表现,结合相关的临床资料,对该病的诊断有一定提示作用,确诊依赖病理。
Objective To investigate the characteristics of multi-slice spiral CT (MSCT) in primary clear cell carcinoma of the liver (PCCCL). Materials and Methods The clinical and MSCT data of 8 patients with PCCCL confirmed by pathology were retrospectively analyzed. Results Eight patients had a history of hepatitis B, of which 7 were male and 6 were negative for alpha fetoprotein (AFP). Eight cases were single lesions, 6 lesions occurred in the right lobe of the liver, mostly round, oval or shallow sub-leaf, no capsule, the border is unclear, mainly solid components, necrosis visible in the tumor. CT plain scan shows that the solid part of the tumor is low density or isodensity. CT double-enhanced scan, 5 lesions showed mild enhancement, the edge of the lesion was enhanced significantly, 1 lesion showed uneven patchy enhancement; 2 lesions were typical rapid hematocrit "Strengthening method; 1 lesion was significantly enhanced, portal venous phase enhancement was higher than the arterial phase; the necrotic area of the lesion center was not enhanced. Conclusion The imaging features of PCCCLMSCT, combined with relevant clinical data, have a certain prompting effect on the diagnosis of this disease. The diagnosis depends on pathology.
