case_images: The initial kidney ultrasonography (USG) performed on admission day revealed variable sized renal cysts on both kidneys and an 8.8 cm multiseptate cystic mass on the mid-lower pole of the right kidney (Figure 1).
case_images: Serial section of computed tomography (CT) showing numeral cysts on liver (A,B) and upper pole of both kidneys (C,D) and 10 cm sized huge cystic mass with well-enhancing wall from mid-lower pole of right kidney (E-H).

case_images: Mass was limited to the kidney and there was no lymph node enlargement, invasion into major veins or perinephric tissues, and distant metastasis (T2a, N0, M0, stage II) (Figure 2). Upon sectioning the kidney, distortion of the normal architecture by xanthomatous nodules and dilated pelvicocalyces filled with pus and blood were observed (Figure 2).
case_images: The gross specimen showed distortion of the architecture by xanthomatous nodule (arrow), and dilated pelvi-calyceal system filled with pus and blood (A,B). Microscopic finding revealed infiltration of neutrophils and lipid-laden macrophages (C) (H/E, x400). Lipid-laden macrophage was diffusely stained for CD68 (D) (x400).
