History of tuberous sclerosis, evaluate kidneys for angiomyolipomas and cysts. Note that this examination is protocoled for evaluation of the kidneys and as such portions of the upper abdomen are excluded from the field-of-view.ABDOMEN:LUNG BASES: Trace basilar atelectasis.LIVER, BILIARY TRACT: The visualized portion of the liver demonstrates normal parenchymal signal intensity without focal lesions.SPLEEN: The visualized portions of the spleen appears normal.PANCREAS: The pancreatic parenchyma demonstrates normal signal intensity and enhancement without focal lesions.ADRENAL GLANDS: The adrenal glands appear normal.KIDNEYS, URETERS: There are scattered 1-2 mm cystic lesions throughout both kidneys which are too small to characterize but do not demonstrate suspicious features. It is estimated that approximately 20 of these cysts are present in each kidney. A representative lesion in the right lower pole (series 501, image 8) measures 2 mm. No evidence of angiomyolipoma. There is no evidence of hydronephrosis. The kidneys demonstrate normal parenchymal enhancement and excretion of contrast.RETROPERITONEUM, LYMPH NODES: No retroperitoneal lymphadenopathy is identified.BOWEL, MESENTERY: The visualized bowel is not significantly dilated.BONES, SOFT TISSUES: The visualized osseous structures appear normal.OTHER: A trace amount of free fluid is present within the pelvis.
