Renal Infarction Imaged With [18F]Prostate-Specific Membrane Antigen-1007 PET/CT.

Abstract: A 61-year-old post-renal transplant man developed pain in the region of the allograft 4 days after transplantation. Contrast-enhanced CT scan revealed multiple small perfusion defects in the renal graft cortex. Multifocal renal cortical infarction was suspected. A [99mTc]Tc-DMSA SPECT/CT showed several small regions with decreased uptake. In addition, an [18F]PSMA-1007 PET/CT confirmed these uptake defects and revealed additional defects. The renal cortical infarctions presumably originated from intraoperative emboli emerging from the arterial anastomosis. Treatment with acetylsalicylic acid 100 mg led to favorable evolution of the renal function biochemically. Follow-up DMSA scintigraphy 3 months later showed resolution of the renal cortical defects.
