Bilateral diffuse involvement of the kidneys with multiple differential densities. The right-sided mass measures 125 x 163 mm and the left-sided mass 130 x 145 mm. Both masses have fatty components with CT density -33 HU. Contrast-enhanced scans show patchy and heterogeneous enhancement in the soft tissue and vascular component of the mass lesions. Normal excretion of contrast media was seen on both sides. Multiple areas of blood densities are noted on the right side suggesting haemorrhage. The uterus remains sub-involuted.
