Renal lipomatosis was diagnosed in a kidney transplant recipient who presented with acute kidney injury (AKI) several years after transplantation. The patient had an odd-looking kidney transplant on ultrasound and computed tomography (CT) scan, showing a medullary mass with resultant compression of the surrounding renal parenchyma. A biopsy of the renal medulla confirmed fatty infiltration of the renal parenchyma. The patient underwent percutaneous nephrostomy and AKI resolved with relief of the obstruction. Renal lipomatosis is a rare condition that should be differentiated from other neoplasms of the kidney. When it occurs in a functioning transplant kidney, the treatment approach proves to be very challenging.
肾脂肪增多症在一名肾移植受者中被诊断出来，该患者在移植数年后面临急性肾损伤（AKI）。患者的肾脏移植在超声和计算机断层扫描（CT）上看起来异常，显示髓质有肿块，导致周围肾实质受压。肾髓质活检证实肾实质存在脂肪浸润。患者接受了经皮肾造瘘术，急性肾损伤随着梗阻的解除而得到缓解。肾脂肪增多症是一种罕见的病症，应与其他肾脏肿瘤相鉴别。当它发生在有功能的移植肾中时，治疗方法极具挑战性。
