Fig. 1.
Well-demarcated lesion in the dorsal aspect of the left kidney; strong, rather peripheral contrast enhancement in the early arterial phase
Fig. 2.
Renal capsule distorted by the focal mass; coronal CT reconstruction clearly indicated extra-tumor, subcapsular location of the fatty tissue described initially as a component of AML
Fig. 3.
B-mode image of the well-demarcated, heterogeneously hyperechoic focal lesion within the renal cortex
Fig. 4.
No apparent flow signals consistent with vascularization of the lesion; prominent modeling of the renal vessels at the tumor margin visible in color Doppler images
Fig. 5.
Intense contrast enhancement of the lesion in the early arterial phase is visible on CEUS images (10 seconds from contrast administration)
Fig. 6.
Relatively earlier contrast washout compared to the surrounding normal renal parenchyma is visible on CEUS images (after 2:50 minutes from contrast administration)
