Abstract
Renal angiomyolipoma is recognised as a benign hamartomatous lesion with no obvious malignant potential. However, the tumour may show extrarenal/perinephric extension at times. Rarely, the lesion may extend into the renal vein and inferior vena cava (IVC) indicating aggressive behaviour. We present a case of an angiomyolipoma of the kidney with sonographic, CT and MRI evidence of extension into the renal vein and IVC.
摘要
肾血管平滑肌脂肪瘤被认为是一种良性错构瘤性病变，没有明显的恶性潜能。然而，肿瘤有时可能会向肾外/肾周延伸。罕见情况下，病变可能延伸至肾静脉和下腔静脉（IVC），提示具有侵袭性行为。我们报告了一例肾血管平滑肌脂肪瘤的病例，其超声、CT 和 MRI 均显示延伸至肾静脉和 IVC。
