Angiomyolipoma (AML) consists of <10% of all renal tumors and is the most common benign mesenchymal neoplasm of the kidney. It arises from the renal cortex and extends toward perirenal fat. Fat-poor AML as well as those arising from rare locations may pose diagnostic difficulties. In our case, we report a rare presentation of this tumor arising from the renal sinus extending toward the pelvis thereby leading to an alternative diagnosis of transitional cell carcinoma of renal pelvis.
血管平滑肌脂肪瘤（AML）占所有肾肿瘤的比例不到10%，是肾脏最常见的良性间叶性肿瘤。它起源于肾皮质并向肾周脂肪延伸。脂肪含量少的AML以及起源于罕见部位的AML可能会造成诊断困难。在我们的病例中，我们报告了这种肿瘤的一种罕见表现，它起源于肾窦并向肾盂延伸，从而导致肾盂移行细胞癌的误诊。
