I see reasonably normal shape and size kidneys with cortical striations and a pronounced medullary rim sign.  Can you tell whether this is more likely congenital vs. toxic/infectious from these images?  They don’t look like the renal dyplasia cases I’ve seen previously but I know they can vary in appearance some.

Thanks!

I am having trouble getting really dark images when I export so hopefully you can read them, still sorting out technical issues.
