Incidental detection of increased (18)F-FDG uptake and its follow-up in patients with granulomatous prostatitis after BCG treatment for urinary bladder cancer.
Incidental prostate uptake of fluorine-18-fluorodeoxyglucose in positron emission tomography/computed tomography ((18)F-FDG PET/CT) may represent malignancies like prostate malignancy, inflammation or benign prostatic lesions. We report two cases of bacillus Calmette-Guérin (BCG)-induced granulomatous prostatitis that showed (18)F-FDG uptake of the prostate gland on (18)F-FDG PET/CT in patients who had previously received intravesical BCG treatment for bladder cancer. The degree of (18)F-FDG uptake was decreased on the follow-up PET/CT scan after one year, without any specific treatment.
