“Snake in the Scrotum Sign”: Reappraising the Potential of 18F-FDG PET/CT in Post–Renal Transplant Patient with Pyrexia of Unknown Origin

18 F-FDG PET/CT, the workhorse of oncological imaging has changed the diagnostic and management paradigm in cases of fever and inflammation of unknown origin, with diagnostic superiority over the conventional imaging modalities. Various complications like acute and chronic graft pyelonephritis, acute rejection, infections, and surgery-related complications can occur post-renal transplantation. The authors in the present study demonstrate coexisting graft pyelonephritis, prostatitis, epididymo-orchitis, and funiculitis on 18 F-FDG PET/CT in a patient, post renal transplant with clinical presentation as pyrexia of unknown origin.
