History of tuberous sclerosis with angiomyolipomas. Evaluate for interval change. ABDOMEN:LIVER, BILIARY TRACT: Right liver lobe multiseptated cystic lesion is unchanged, measuring 3.6 x 2.5 cm. Punctate additional hyperintense foci, likely cysts. No evidence of intra or extrahepatic biliary ductal dilatation. Normally distended gallbladder.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Partially duplicated right collecting system. No evidence of hydroureteronephrosis.Postsurgical changes from partial left nephrectomy.The right renal interpolar exophytic enhancing lesion measures approximately 2.5 x 1.9 cm (series 12/49), compared to 2.4 x 2.7 cm previously.The more inferior lesion measures approximately 1.1 by x 0.7 cm (series 12/6/1963), compared to 1.1 x 0.8 cm previously. These lesions do not have significant macroscopic fat content.Additional punctate foci are too small to characterize.RETROPERITONEUM, LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Exophytic right renal enhancing lesions are unchanged in size. Given the history of tuberous sclerosis and pathology of partial nephrectomy these lesions likely represent lipid poor angiomyolipomas.2.Postsurgical changes from partial left nephrectomy.
