Huge bilateral solid perirenal masses with hypodense radial striations, insinuating into the renal sinuses and distorting the kidneys. The right mass measures 11.3 x 14.4 x 24.0 cm and the left measures 13.8 x 21.8 x 30.2 cm. There is severe thinning of the renal parenchyma of both kidneys in several places. In the excretory phase (~4 min after the nephrographic phase), contrast material only fills the renal collecting system bilaterally but does not extend into the ureters, possibly due to early timing.
Periaortic soft tissue partially enveloping the thoracic aorta. Rest of thorax (additional study, not shown) normal.
Small hepatic nodule in segment 6, only visible and hypoenhancing in the nephrographic phase - perhaps a hemangioma. Tiny non-enhancing hypodense focus in segment 3 abutting the left hepatic vein - probably a cyst.
Small sliding hiatal hernia.
Tiny adenoma in lateral arm of right adrenal gland, several small adenomas and tiny myelolipoma in left adrenal.
Small hemangioma in the L2 vertebral body.
