Nonspecific granulomatous prostatitis in a 57-year-old male with dysuria and urinary retention for 1 month and a serum PSA level of 13.22 ng/mL. a, b DWI at a b-value of 1400 s/mm2 and ADC maps show a focal nodule with obviously restricted diffusion (arrow) in the left peripheral zone of the prostate. c–e DCE imaging shows early and prolonged enhancement of the nodule (arrow). The appearances of the nodule in a–e result in a PI-RADS score of 4. Note the prostatic hyperplasia in the TZ (☆), which may have caused the symptoms of dysuria and urinary retention
