The examination was performed using contrast harmonic imaging at a low mechanical index of 0,1. The exam was documented by digitally storing the images over 60 s in DICOM format. The images showed a hypervascular mass in relation to the remaining parenchyma of the native kidney with heterogeneous enhancement and pseudocapsule sign (Figure 1).
(CEUS) - Quantitative analysis with time-intensity curve. In the
arterial phase, the mass was considered hypervascular when compared to
the remaining parenchyma.

Left - The 2.5 cm diameter tumor was reddish-brown, lighter than
cortex, with well-circumscribed borders that mimics a capsule, and
without central scar. In addition, there were multiple coalescing small
grayish nodules scattered throughout the mass. Right - microscopic
findings showed numerous tubular cells with abundant granular cytoplasm
and large nuclei.
