摘要
目的探讨成人肝母细胞瘤的cT和MRI表现特征。方法回顾性分析8例成人肝母细胞瘤CT和MRI表现，观察影像学与手术的吻合情况。结果（1）肿瘤位于肝右叶占75．0％，肝左叶占25．0％。（2）瘤体最大径平均（8．2±5．5）cm，其中最大径〉5cm占62．5％。（3）肿瘤有完整或不完整假包膜，界限较清楚。（4）肿瘤坏死囊变占75．0％，钙化或出血仅占25．0％。（5）cT平扫示均匀低密度或等低密度，MRI平扫T，WI呈低信号，T，WI、T，WI脂肪抑制和DWI上实质部分呈高信号。（6）增强动脉期实质部分呈轻、中度不均匀强化或轻度环形强化，门静脉期持续轻度强化，延迟期缓慢退出占75．0％，仍持续强化占25．0％，假包膜均持续轻度强化。（7）相邻器官受压变形。（8）8例患者均接受肿瘤切除术并随访3～24个月。结论掌握成人肝母细胞瘤CT和MRI的特征性，有助于提高该病的诊断准确率。
Objective To investigate CT and MRI features of hepatoblastoma in adults. Methods CT and MRI findings of 8 cases of adult hepatoblastoma were retrospectively analyzed. Results （ 1 ） 75.0% of the tumors was located in the right lobe of the liver and 25.0% in the left lobe of the liver. （2） The maximum diameter of the tumor was averaged at （8.2 ± 5.5 ） cm, and the maximum diameter of 〉 5 cm was 62. 5%. （3） Most tumors have a complete or incomplete false envelope, and the boundary is clear. （4） 75.0% tumors were of necrocystic degeneration with calcification or bleeding in 25.0% cases. （5） CT fiat scan showing uniform low density or low density, MRI scanning TIWI was low signal, T2WI, T2WI fat suppression and DWI were high in parenchyma. （6） To strengthen substantial part in mild and moderate arterial uneven improved or ring slightly improved, portal venous phase continued mild reinforcement, delay slow exit accounted for 75.0%, reinforced psuedocapsule was mild. （7） The adjacent organs are under pressure deformation. （8） All patients underwent tumor resection and were followed up for 3 to 24 months. Conclusions CT and MRI characteristics of hepatblastoma in adult are specific and help improve the diagnostic accuracy of the disease.
