83-year-old male with a history of a left renal complex cysts (Bosniak 3). Follow-up examination. ABDOMEN:LIVER, BILIARY TRACT: There is a focus of nonenhancing linear increased T2 signal abnormality in the right lobe of the liver, which is nonspecific.SPLEEN: No significant abnormality noted.PANCREAS: No significant abnormality noted.ADRENAL GLANDS: No significant abnormality noted.KIDNEYS, URETERS: Note is made of a 2.8 x 2.6 cm complex cystic lesion along the lateral aspect of the interpolar region of the left kidney, with associated increased T1 signal abnormality (22; series 6). There is a thick septation which enhances on postcontrast sequences.Note is made of a complex cyst in the superior pole of the left kidney, with associated increased T1 signal abnormality. Multiple additional subcentimeter foci of fluid signal intensity are identified within the kidneys bilaterally, which are too small to characterize, but likely represent simple cysts. No evidence of hydroureteronephrosis.RETROPERITONEUM, LYMPH NODES: No evidence of lymphadenopathy.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
