Fig. 1From: Fat-poor angiomyolipoma with cyst-like changes mimicking a cystic renal cell carcinoma: a case reportPreoperative computed tomography. The renal mass appears mainly as a hypodense area (a) with a partially hyperdense area (d) on unenhanced computed tomography. The hyperdense area and septa are enhanced in the early phase (b, e) and washed out in the late phase (c, f). White arrows show the area where CT attenuation value is calculatedBack to article page
