83 year old male patient with history of right-sided renal mass. Evaluate for changes. RENAL TRANSPLANT: LOCATION: Right iliac fossa.PERITRANSPLANT TISSUES: No perinephric fluid collection is identified.KIDNEY: Renal cortical echogenicity is within normal limits.COLLECTING SYSTEM/URETER: No evidence of hydronephrosis.URINARY BLADDER: No significant abnormality notedVASCULAR DOPPLER DATA: Color Doppler imaging of the transplant kidney is within normal limits.OTHER: There is a 2.1 x 1.9 cm hypoechoic mass within the superior pole of the right native kidney which appears to correlate with previously identified right renal mass. Given differences in modality/technique, the mass appears similar in size to the prior study. An additional subcentimeter hypoechoic lesion is noted.
1. Similar size of a previously identified mass within the native right kidney given differences in modality/technique when compared to prior CT.2. Unremarkable transplant kidney.
