The above 3 ultrasound images reveal a hypoechoic collection lateral to the left corpus cavernosum of the penis following penile trauma. Color doppler image reveals a possible source of the hemorrhage. There is evidence of rupture of the lateral aspect of the tunica albuginea of the penis. Images reveal a transverse section of the affected part. Case and images courtesy of Mr. Shlomo Gobi, Israel.

4) Penile fracture:

hematoma around the penis      rupture of tunica albuginea

fracture of the penis  

The above ultrasound images reveal a hypoechoic collection (hematoma) with rupture of the tunica albuginea covering the left corpus cavernosum. Fracture of the penis is caused by trauma to an erect penis, resulting in rupture of the corpus cavernosum and the tunica albuginea covering it. Usually, the left corpus cavernosum is affected.

5) Low flow Priapism:

dorsal artery of the penis     dorsal vein

power doppler shows no flow in corpus cavernosum     poor flow in cavernosal artery of penis

the dorsal vein of penis    transverse section of the penis

(CC= corpus cavernosum, CS= Corpus spongiosum, Dorsal V= dorsal vein of penis, Cav A= cavernosal artery)

This middle aged male patient presented with painful persistent erection (priapism) since 6 days. He did not have any history of trauma. Sonography, power doppler and color doppler imaging of the penis revealed poor flow or absent flow in the cavernosal artery of the penis with moderate flow in the dorsal artery and vein. There is also no flow within the corpora cavernosa of the penis. The ultrasound and color doppler images are diagnostic of low flow priapism. Images taken by Joe Antony, MD, India, using a Toshiba Nemio- XG ultrasound system.
