摘要
目的:分析高分化肝癌的CT征象,以期提高该病的诊断及鉴别诊断水平。方法:回顾性分析18例经手术病理证实的高分化肝癌的CT表现。结果:18例中单发17例,多发1例,共19个病灶;病灶形态规则11个,浅分叶状8个,平均最大径(4.27±0.50)cm;8个病灶可见假包膜结构;13个病灶行三期增强扫描,相对于周围正常肝组织,病灶三期强化模式归纳如下:6个病灶呈高密度-低密度-低密度,3个病灶呈等/低密度-低密度-低密度,4个病灶呈高密度-高密度-高/等/低密度。结论:高分化肝癌MSCT增强表现多样,诊断时应密切结合临床资料,并与肝脏其他占位性病变相鉴别。
Objective：To analyze the multi-slice computerized tomography（MSCT） findings of well-differentiated hepatocellular carcinomas to improve the diagnostic level.Methods：CT scanning features of 18 well-differentiated hepatocellular carcinomas cases,proved by operation and pathology,were retrospectively analyzed.Results：Among the 19 lesions of the 18 cases,11 lesions showed regular shape,9 lesions appeared lobulated.The mean maximal diameter of the masses was（4.27±0.50）cm.Capsule was observed in 8 lesions.13 lesions which underwent three-phase enhanced CT scanning showed different enhancement pattern as follows：6 lesions appeared hyperdense-hypodense-hypodense,3 lesions appeared iso-/hypodense-hypodense-hypodense,4 lesions appeared hyperdense-hyperdense-hyper-/iso-/hypodense,compared with the surrounding normal hepatic tissues.Conclusion：Enhancement MSCT findings of well-differentiated hepatocellular carcinomas have various manifestations.Accurate diagnosis of well-differentiated hepatocellular carcinomas needs combination with medical history and differentiation with other space-occupying lesions of liver.
