The structures appearing as hypoechoic vesicles on ultrasound located superior to the prostate and posterior to the bladder are which?

• A. Seminal vesicles
• B. Cowper's glands
• C. Prostatic utricle
• D. Epididymis

Answer: (A)

Seminal vesicles. These paired, fluid-filled structures sit behind the bladder and above the prostate. On ultrasound they appear as two elongated, hypoechoic vesicles with thin walls in the space posterior to the bladder. This position—superior to the prostate and posterior to the bladder—matches the seminal vesicles exactly. Cowper's glands are smaller and located lower near the urethra, the prostatic utricle is a midline structure within the prostate, and the epididymis lies in the scrotum, not in this pelvic location.
