Angiomyolipoma is a benign tumor consisting of abnormal vessels, smooth muscles, and fatty tissue. Renal cell carcinoma is an insidious neoplasm accounting for approximately 2% of global cancer diagnoses. Due to similar diagnostic features, the differentiation between the two types is sometimes difficult. We hereby present the case of a 60-year-old patient with no clinical symptoms and a focal lesion in the parenchymal layer of the left kidney incidentally detected on ultrasound examination. The putative diagnosis was angiomyolipoma, which was then confirmed by another ultrasound and computed tomography examinations. However, a further radiologic consultation revealed another probable diagnosis - renal cell carcinoma. Contrast-enhanced ultrasound was conducted, and the enhancement pattern was suggestive of cancer. To sum up, a thorough imaging examination plays an important role in the diagnostic work-up of neoplastic lesions in the kidney. Even then, however, the radiological image of the lesion may be misleading, so differential diagnosis is important for making a proper diagnosis.
血管平滑肌脂肪瘤是一种由异常血管、平滑肌和脂肪组织组成的良性肿瘤。肾细胞癌是一种隐匿性肿瘤，约占全球癌症诊断病例的2%。由于诊断特征相似，有时很难区分这两种类型。我们在此报告一例60岁患者，无临床症状，超声检查偶然发现左肾实质层有局灶性病变。初步诊断为血管平滑肌脂肪瘤，随后经另一次超声和计算机断层扫描检查得以证实。然而，进一步的影像学会诊显示了另一种可能的诊断——肾细胞癌。进行了对比增强超声检查，增强模式提示为癌症。总之，全面的影像学检查在肾脏肿瘤性病变的诊断检查中起着重要作用。然而，即便如此，病变的放射影像仍可能产生误导，因此鉴别诊断对于做出正确诊断很重要。
