Abstract

From 1989, 15 cases of renal angiomyolipoma (AML) have been diagnosed by ultrasonography. CT scanning and digital subtraction angiography (DSA) at our hospital. In 8 patients with uneven hyperechoes on B-mode ultrasonography (B-US) (8/15) and 7 with low density of fat on CT scanning (7/12) accurate diagnosis was established preoperatively. DSA revealed the "berry-like" pseudoaneurysms in the arterial phase (14 cases), the defined lucent area in the nephrogram phase (10 cases) and the "onion-peel appearances" during venous phases (8 cases), correct diagnosis was achieved in all patients. 8 cases were surgically treated and 7 treated by subselective embolization of renal artery. Effects in all cases were good. The diagnostic value of B-US, CT scanning, DSA and interventional treatment of AML was discussed. It was believed that the diagnosis with DSA was a technique with high specificity, and embolization therapy was simple and effective for AML.

摘要

自1989年以来，我院通过超声检查、CT扫描和数字减影血管造影（DSA）诊断出15例肾血管平滑肌脂肪瘤（AML）。8例患者在B型超声（B-US）上表现为不均匀高回声（8/15），7例在CT扫描上表现为低密度脂肪（7/12），术前得以准确诊断。DSA显示动脉期有“浆果样”假性动脉瘤（14例），肾图期有明确的透亮区（10例），静脉期有“葱皮样表现”（8例），所有患者均得以正确诊断。8例行手术治疗，7例行肾动脉超选择性栓塞治疗。所有病例效果良好。讨论了B-US、CT扫描、DSA对AML的诊断价值及介入治疗。认为DSA诊断是一种特异性高的技术，栓塞治疗对AML简单有效。
