Figure 2a. (a) Longitudinal US image demonstrates a large, moderately echogenic solid mass (M) in the right upper quadrant. The mass appears to be contiguous with the right lobe of the liver (L) and causes mass effect (black arrowhead) on the kidney (K). Scattered small, nonshadowing hyperechoic foci (white arrowhead) are also seen but did not prove to represent calcifications. (b) Doppler US image demonstrates increased peripheral flow within the mass (arrowhead), with the central portion demonstrating much less vascularity.
