Transabdominal ultrasound image showing a small, but clearly visualized solid polypoid tissue projecting into the urinary bladder close to the bladder neck. The query here is: is this mass a bladder mucosal polyp or a beak of prostatic tissue (the patient was a middle aged male with lower urinary tract obstructive symptoms).
Transrectal ultrasound image shows the polypoid mass of 12 x 5 mm. size, emanating from the bladder mucosa close to the prostate. Color Doppler ultrasound shows considerable flow within the urinary bladder polyp. This amount of vascularity is highly suggestive that this mass of tissue is a vascular mucosal polyp and not an enlarged median lobe of prostate.
