Bacillus Calmette-Guerin therapy-induced granulomatous prostatitis on multiparametric magnetic resonance imaging: a case report

摘要

Multiparametric magnetic resonance imaging (MRI) has emerged as a diagnostic tool for the detection of prostate cancer. Studies have demonstrated a significant correlation between suspicious MRI lesions and positive prostate biopsy. Intravesical bacillus Calmette-Guerin (BCG) therapy is routinely performed as a treatment for patients with non-muscle invasive bladder cancer, which may result in granulomatous prostatitis (GP) as a side effect. Currently, the only way to distinguish GP from prostate cancer is by biopsy confirmation.
