case_images: B-Mode US scan of the heterogeneous, cystic-solid mass involving the entire left kidney. The size of the lesion in three planes is 60x59x64 mm.

case_images: Ultrasonography revealed an ovoid shaped 60x59x64 mm 3 sized, heterogeneous mass consisting of intermediate echogenicity (Figure 1).
case_images: Sonographic posterior acoustic enhancement of the semi-solid cystic mass is clearly seen.

case_images: The central region was composed of an irregular hypoechoic component with posterior acoustic enhancement (Figure 2).
case_images: Nodular protrusion of the solid component towards the central region and anechoic-cystic central component is seen. Calcifications are not remarkable in US.

case_images: Faint nodular protrusions from the peripheral solid component into the hypoechoic center were seen (Figure 3).
case_images: Helical CT examination of heterogeneous, cystic renal mass within the left retroperitoneal site shows peripheral fatty tissue deposits with low attenuation values.

case_images: CT demonstrated a lobulated, heterogeneous, hypodense mass extending craniocaudally from the splenic hilum to the level of the left iliac fossa (Figure 4).
case_images: A, Peripheral coarse calcifications on CT. B, Calcifications are clustered in particular regions of the mass.

case_images: Peripheral hyperdense coarse calcifications and adipose tissue components were well demonstrated by CT, with clusters of calcific foci (Figure 5).
