56-year-old male with left renal lesion on CT. RIGHT KIDNEY: The right kidney measures 9.4 cm in length. The renal cortex is echogenic. Subcentimeter midpole cyst measures 0.9 x 0.6 x 0.7 cm.LEFT KIDNEY: The left kidney measures 9 cm in length. The renal cortex is echogenic. Previously described mid pole lesion on CT is anechoic and demonstrates posterior through transmission, most likely a cyst. This lesion measures 2.0 x 2.0 x 2.3 cm.URINARY BLADDER: The bladder is collapsed with a thickened wall.OTHER: No significant abnormalities noted.
