Concurrent Diffuse Pyelonephritis and Prostatitis Discordant Findings on Sequential FDG PET/CT and Ga-67 SPECT/CT Imaging

摘要

A 45-year-old man underwent FDG PET/CT for initial imaging evaluation of recurrent Escherichia coli urinary tract infections, which demonstrated no significant FDG uptake in either kidney and subtle FDG uptake in the right prostate lobe. Subsequent Ga-67 SPECT/CT demonstrated abnormal intense gallium uptake throughout the right kidney and entire prostate gland, clearly discordant with PET/CT findings and consistent with unexpected concurrent pyelonephritis and prostatitis. Although FDG has effectively replaced Ga-67 in everyday clinical practice, the current case serves as a reminder that there is still a role for Ga-67 in the evaluation of genitourinary infections.
