Core Tip
Core Tip: Granulomatous prostatitis is a rare complication of BCG instillation, which can easily be misdiagnosed as prostate cancer. Here, we report a 64-year-old Chinese man with BCG-induced granulomatous prostatitis that resembles prostate cancer. Although histopathology remains the gold standard to accurately differentiate between the two diagnoses, some clues such as temporarily elevated PSA levels and a high signal followed by a low-signal abnormality on high b-value diffusion-weighted MRI are important indicators of BCG-induced granulomatous prostatitis.
