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. |
