Child Genu

Challenge: The first image is normal. What does the second image show?

Images shown under Fair Use.

it looks like a normal kidney, the second image shows a kidney, normal in size, with multiple "lesions" which are homogenous and do not reflect ultrasounds, but have an enhanced ultrasound cone behind them (posterior echo enhancement) which tells us that it must be aqueous in nature. this could be a polycystic kidney.
If the second kidney is similar this might be due to the polycystic kidney disease. (genetical aberration)
in which one should ask the question which type it is. whether it is dominant or recessive type 1 or 2, and whether the liver is affected.
It doenst seem to be a childrens kidney (too big) , this might help find out which type it is, as one typically presents itself in childhood already

i hope I'm on the right track

yeah - you're on the right track. honestly, i am no expert in reading renal ultrasounds so i can't tell you how to tell the difference between dilated calyces and polycystic kidney disease...nice job
Child Genu

What’s child genu? A bad pun for kidney. The first image is a normal renal ultrasound with hypoechoic parenchyma surrouding echogenic renal sinus. The second image shows hydronephrosis with dilated calyces (C) within the renal sinus.
