摘　　要：目的探讨少血供不典型小肝癌(SHCC)的CT表现及其病理学基础。方法回顾性分析经手术病理证实的6例少血供不典型肝细胞肝癌的CT表现,并与病理结果对照研究。结果 6例平扫及其三期增强扫描相对于邻近正常肝实质均呈低密度,平扫4个病灶边界模糊,2个病灶边界清楚,2个有纤维假包膜,4个病灶密度均匀,2个病灶密度不均匀;增强后动脉期3个病灶边界清,3个病灶边界模糊,门脉期只有1个病灶边界模糊,同时病灶边缘轮廓轻度不规整,2个密度均匀,4个密度不均;6例中仅1例为低分化,5例为中分化。结论少血供SHCC的CT表现不典型,其不典型原因与病灶的血供情况、病理学基础等有关。Objective To explore the CT performance of hypovascular atypical small hepatocellular carcinoma （SHCC） and its patho- logical basis. Methods CT performance of 6 cases of hypovascular atypical small hepatocellular carcinoma confirmed by surgical pathology was retrospectively analysed, and control study with pathological results was conducted. Results Six cases of unenhanced and three enhanced scanning showed low density compared with the adjacent normal liver parenehyma. Plain scanning of four lesions showed fuzzy boundary, twolesions had clea, boundary, two had fiber false envelope, four lesions showed uniformity in density and two lesions had uneven density; in en- hanced arterial phase, three lesions had clear boundary, and three lesions had fuzzy boundary. In portal period only one lesion had fuzzy boundary, and at the same time, lesion＇s edge profile was mildly irregular, 2 showed uniformity in density, anti four had uneven density. Only 1 case among 6 cases was poorly differentiated, and 5 cases showed moderate differentiation. Conclusion Hypovascular CT features of small hepatocellular carcinoma are not typical, which results from the blood supply of lesions, the pathological foundation and so on.
