tuberous sclerosis and history of embolization of right kidney angiomyolipoma. ABDOMEN:LIVER, BILIARY TRACT: No focal hepatic mass. No intra or extra hepatic biliary ductaldilatation. The gallbladder is normal in appearance.SPLEEN: Heterogeneous foci scattered throughout the spleen may reflect splenic hamartomas and are unchanged from prior examination. PANCREAS: No significant abnormality noted.ADRENAL GLANDS: The adrenal glands are not well visualized.KIDNEYS, URETERS: Large heterogeneous mass occupying the majority of the upper and midpoleof the right kidney that now appears confluent with the inferior pole. The mass measures 6.1 x 7.2 cm in axial dimension (series #401, image 22). The previously described blood vessel that appeared the periphery of this mass remains present, but is significantly decreased in size when compared to prior examination.There is a slightly smaller mass occupying the inferior pole anteriorly with only a smallamount of renal parenchyma remaining. The mass measures approximately 4.2 x 5 cm (series #401, image 13). The mass effect on the inferior vena cava has significantly improved when compared to prior examination. Innumerable bilateral T2 hyperintense foci compatible with renal cysts. Additional hypointense foci bilaterally compatible with angiomyolipomas. The largest of which on the left measures 3.2 x 2.1 cm (series 401, image 17). Retroaortic left renal vein, unchanged. RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Bilateral dependent atelectasis in the partially visualized lung bases.
1. Heterogeneous right renal masses with interval decrease in size when compared to prior examination. 2. Multiple renal cysts, left angiomyolipomas, and splenic hamartomas are unchanged.
