Is this an intravenous pyelogram?
No.
Is this a renal arteriogram?
Nope.
Was any contrast used here at all?
No.
This patient suffers from familial
hyperoxalosis with renal
osteodystrophy.
So what are
these?
There is an increased rate of oxalate synthesis in the body.
Calcium binds to oxalic acid to form calcium oxalate,
which is insoluble.
The result is a buildup of calcium oxalate
in renal tissues, and
the kidneys become
effectively calcified.
Treatment can
involve renal
transplantation.
