目的评价CT在儿童肝母细胞瘤诊断中的价值。方法总结12例临床影像资料完整、经活检或手术病理证实的肝母细胞瘤的临床CT表现。结果肿瘤位于肝右叶5例,左叶1例,跨越左右叶6例。平扫肿瘤均呈单发低密度,巨大肿瘤内可见多发裂隙状及不规则形更低密度区;肿瘤内斑片、点线状钙化6例。增强扫描9例肿瘤动脉期呈多个结节状或片状强化,密度高于肝组织,门脉期病灶呈低密度;3例肿瘤动脉期、门脉期均呈低密度;包膜强化4例,瘤内可见迂曲血管3例,伴有腹水1例。结论肝母细胞瘤的CT征象具有一定特征性,CT对肝母细胞瘤的诊断有重要价值。
Objective To evaluate the value of CT in the diagnosis of childhood hepatoblastoma. Methods The clinical manifestations of 12 hepatoblastomas with complete clinical images and confirmed by biopsy or surgical pathology were summarized. Results The tumor was located in 5 cases of right lobe, 1 case of left lobe and 6 cases of left and right lobe. Tumors were single scan showed low density, large tumor can be seen multiple fissures and irregular shape of the lower density area; tumor plaque, dot line calcification in 6 cases. Nine cases of enhanced tumor scan showed multiple nodular or patchy arterial phase, with higher density than the liver tissue, with low density in the portal venous stage. Three cases showed low density in the arterial phase and portal venous phase. For example, tortuous blood vessels seen in 3 cases, with ascites in 1 case. Conclusions CT signs of hepatoblastoma have certain characteristics. CT is of great value in the diagnosis of hepatoblastoma.
