摘　　要：目的　分析小肠平滑肌类来源肉瘤肝转移的CT表现和肝动脉造影表现。材料与方法　回顾性分析 7例小肠平滑肌类肉瘤肝转移病例 ,肝脏转移肿瘤共 46个。 7例均行肝脏CT三期扫描和肝动脉造影。结果　肝脏转移病灶CT平扫呈低密度实性或囊实性占位。肿瘤膨胀生长 ,与周围肝实质分界清楚。动脉期增强扫描肿瘤实质部分明显强化 ,门脉期与周围肝实质强化差异缩小。肿瘤囊变坏死区无强化。肝动脉造影示转移肿瘤血管和染色丰富。结论　小肠平滑肌类来源肉瘤肝转移以肝动脉供血为主 ,为富血供肿瘤 ,类似于肝细胞癌。Objective To analyze the CT and angiographic findings of hepatic metastases from small intestinal leiomyosarcoma.Materials and Methods CT features of 46 hepatic metastatic lesions in 7 patients with small intestinal leiomyosarcoma were retrospectively analyzed. CT tri phase scanning and hepatic arterial angiography were performed in all patients.Results All the metastatic lesions appeared as low density masses, some of which were solid and some were cystic with mixed density.
