摘要
目的 探讨肝脏血管平滑肌脂肪瘤 (HAML)的影像诊断、鉴别诊断、外科及介入治疗。方法 分析 8例HAML的临床、影像学表现和治疗方法。结果 本组有以下影像表现 :①超声为边界清楚的强回声肿块 ;②CT、MRI为有明确脂肪密度或信号的肿块 ,明显强化 ;③DSA为血供丰富 ,早期肝静脉引流 ,染色明显。治疗结果 :5例手术切除 ,随访 6～ 113个月未见肿瘤复发。 1例介入治疗 ,随访 42个月病灶缩小。 2例随访 10个月 ,肝脏病灶无变化。结论 HAML的影像学表现有一定特征性 ,HAML应首选外科治疗 。
objective To evaluate imaging diagnosis, differential diagnosis, and surgery and interventional therapy of hepatic angiomyolipoma(HAML). Methods Clinical and imaging appearances and therapy of 8 cases HAML were retrospectively analyzed. Results The imaging features: ①a hyperechoic mass with a sharp margin ultrasonography; ② a well defined, fat density or intensive mass on computerized tomograph(CT) and magnetic resonance imaging(MRI) , a marked enhanced mass after intravenous contrast medium;③ a hypervascular mass, early drainage of hepatic vein and tumor stain on angiography. Result of therapy: five cases whose tumors resected were well during the following 6 to 113 months;a tumor treated with interventional therapy diminished after 42 months; the other two tumors had no change within a follow up period of 10 months. Conclusion The imaging appearances of HAML are relatively characteristic. Surgery was the choice of treating HAML and superselective arterial embolization was effective to HAML complicated with tuberous sclerosis.
