A 45-year-old man presented with an incidentally discovered benign renal angiomyolipoma. This lesion initially demonstrated renal vein involvement. On referral to our institution 3 years later, there was interval progression of tumor thrombus to the intrahepatic inferior vena cava. Intravascular extension of benign angiomyolipoma, though rare, has been reported. We present a new example and review the literature concerning this unusual complication of a common renal neoplasm.
一名45岁男性因偶然发现的良性肾血管平滑肌脂肪瘤前来就诊。该病变最初显示肾静脉受累。3年后转诊至我院时，肿瘤血栓已进展至肝内下腔静脉。良性血管平滑肌脂肪瘤的血管内扩展虽罕见，但已有报道。我们展示了一个新病例，并回顾了关于这种常见肾肿瘤不寻常并发症的文献。
