We report a case of 63-year-old man who had urinary tract infection with septic shock, Klebsiella pneumoniae bacteremia, and bacteriuria. (67)Ga SPECT/CT showed hot uptake in prostate gland, and acute bacterial prostatitis was diagnosed. After antibiotic treatment, follow-up (67)Ga SPECT/CT revealed much less uptake in the prostate gland, suggesting remission of prostatitis.
