Abstract

We report here three cases of granulomatous prostatitis. All cases were confirmed by a transrectal ultrasonography (TRUS)-guided core biopsy of the prostate. Two cases received intravesical BCG therapy for a bladder tumor, and one case had no known predisposing condition. Gray-scale TRUS showed low echoic nodules in the outer gland in all cases. Color Doppler ultrasonography (CDUS) showed several dot-like blood flows within the low echoic nodules in two cases and several dot-like blood flows and short linear blood flows within the low echoic nodules in one case. Gray-scale TRUS findings of granulomatous prostatitis are similar to findings of prostate cancer. On CDUS, several dot-like blood flows or short linear blood flows were noted within the low echoic nodules in patients with granulomatous prostatitis. If low echoic nodules with dot-like or short linear blood flows are noted in patients with genitourinary tract tuberculosis or previous BCG therapy, granulomatous prostatitis should be included in the differential diagnosis. However, a prostatic biopsy is required for a final diagnosis.
