Ultra-sound of the kidneys of patient CA (UCY2069 on Fig. 1), aged 57-yrs, presently on ESRD. Both Kidneys are smaller than normal, measuring Rt kidney 8.88 cm in long diameter and the Lt kidney 9.51 cm, with increased echogenicity and cortical thinning, cortex measuring about 0.88 cm. There is no polycystic kidney disease (pelvocalyceal dilatation). Multiple cortical cysts are noted in both kidneys, about 6–8 cysts in each kidney, the bigger to the Rt about 4.5 cm and to the Lt about 3.6 cm. The cysts however have been present at least since 4-yrs, according to the patient’s medical record, at the time his renal function was much better (MDRD 50 ml/min)
