Granulomatous prostatitis: A pitfall in endorectal MR imaging and 3D MR spectroscopic imaging

Granulomatous prostatitis is a benign inflammatory condition of the prostate which can be mistaken for prostatic carcinoma both clinically and on imaging findings. In MR imaging, granulomatous prostatitis has been shown to cause signal intensity decrease in the prostatic peripheral zone similar to carcinoma on T2-weighted sequences. The recent introduction of 3D MR spectroscopy (3D MRS) into clinical practice adds information to the...
