Info

Irregular amorphous calcific densities overlying the left and right iliac fossa, consistent with known failed prior renal transplants.
Case Discussion
Failed renal transplants may develop dystrophic calcifications and although amorphous calcifications in the pelvis would generally warrant a differential, the typical location and the (hopefully) available clinical history should help point you in the right direction.
