We report MR imaging characteristics of a prostatic urethral polyp in a 35-year-old man. Traditionally, the methods of diagnosis include computed tomography, transrectal sonography, voiding cystourethrography, intravenous pyelography, urethroscopy, and cystoscopy. To our knowledge, MR findings have not been previously described. In this case, MR imaging clearly demonstrated a polypoid tumor located in the prostatic urethra with a stalk connected to the bladder neck. A pathological study revealed the polyp consisted of a fibrovascular core covered with a double layered, prostatic-type epithelium.
