title: Radiologic presentation of chronic granulomatous prostatitis mimicking locally advanced prostate adenocarcinoma.
abstract: We present a case of nonspecific granulomatous prostatitis (GP), a clinical mimic of prostate adenocarcinoma. A 54-year-old man presented with lower urinary tract symptoms and raised prostate-specific antigen. Magnetic resonance imaging showed features consistent with prostate cancer, including low T2-signal intensity in the peripheral and transition zones with signs of extracapsular extension. Diffusion-weighted imaging showed high-signal intensity, with low apparent diffusion coefficient values, whereas dynamic contrast enhancement demonstrated a type 3 washout curve, similar to that found in prostate cancer. Transperineal sector-guided prostate biopsy confirmed nonspecific GP, and the patient was treated conservatively. We discuss and compare nonspecific, chronic GP as a radiologic mimic of prostate adenocarcinoma patient.
