Faces of Chronic Renal Failure

CT Chronic Renal Failure Persistent Nephrogram

CT Chronic Renal Failure Persistent Nephrograms
CT in the axial plane through the kidneys shows bilateral small irregular kidneys, left smaller than right with persistent nephrograms a day after a cardiac catheterization. While the larger right kidney does show some excretion into the calyces, there is no identifiable excretory phase in the left kidney. Neither the aorta nor the IVC has contrast and there is vicarious excretion of contrast in the gallbladder which is further evidence of chronic renal failure.

Polycystic Kidney Disease PCKD

CT with Contrast– Polycystic Kidney Disease PCKD
56-year-old male in chronic renal failure presents with flank pain. CT with contrast shows diffuse cystic changes of near normal sized kidneys with total replacement of the renal parenchyma by small uniformly sized cysts. Multiple calcifications are scattered throughout the parenchyma.

Acquired Cystic Disease of Chronic Renal Failure

Acquired Cystic Disease of Chronic Renal Failure
67 year old male with chronic renal failure. Reconstruction of a CT in the coronal plane shows bilateral diffuse small cysts consistent with the diagnosis of acquired cystic disease of chronic renal failure. Although the craniocaudal span is only mildly reduces there is significant parenchymal thinning and renal sinus lipomatosis. Noted ascites from peritoneal dialysis

Acquired Cystic Disease of Chronic Renal Failure
67 year old male with chronic renal failure. CT in the axial plane shows bilateral diffuse small cysts consistent with the diagnosis of acquired cystic disease of chronic renal failure. Noted ascites from peritoneal dialysis as well as induration of the greater omentum. Calcified gallstones are present

Acquired Cystic Disease of Chronic Renal Failure
67 year old male with chronic renal failure. US in the longitudinal plane shows an 11.3cms echogenic kidney with multiple cysts in the 8mm to 10mms range consistent with the diagnosis of acquired cystic disease of chronic renal failure.
