This ultrasound image shows a shotgun lodged deep in the corpus cavernosum of the penis. The pellets are seen as a bright echogenic structures (arrowed). Image courtesy of Dr. Vikas Arora, India.

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.

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.

(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.

This 47 yr. old male patient presented with a palpable nodule on the dorsum of the penis. Clinically, he did not have significant erectile dysfunction but Peyronie disease was suspected. Sonography of the penis was done and showed multiple (4 in number) calcific plaques of the dorsum of the penis, involving the tunica albuginea and also the septum between the corpora cavernosa. There was evidence of significant acoustic shadowing beyond the calcific plaques. The plaques varied in size from 4 mm. to 10 mm. The calcific plaques are shown by arrows in the ultrasound images above. These ultrasound images are diagnostic of Peyronie disease of the penis. Power Doppler imaging (see middle row -left), did not show any altered vascular flow in the penis. Ultrasound images taken using a Toshiba, Nemio-XG system by Joe Antony, M.D., India.

 This patient showed a long calcific plaque of the tunica albuginea of the penis. The transverse section image (color Doppler) showed normal vascularity, but the penile plaque is clearly seen with acoustic shadowing. This is a typical apperance of Peyronie disease. (PLAQ= plaque).

Ultrasound and Doppler images of vascular malformation of the glans penis

 

This male patient aged 50 yrs. presented with a bout of severe hemorrhage from the penile urethra during coitus for the past 2 days. Sonography and Color as well as Power Doppler imaging of the penis was done. Ultrasound/ Doppler flow images show marked vascularity along the glans of penis. Spectral Doppler waveforms show presence of both arterial and venous flow patterns in the vessels in and around the glans penis. These ultrasound, Power Doppler and Color Doppler images of the penis suggest arterio-venous malformation (AVM) in the glans penis. Trauma during coitus would have precipitated this episode of hemorrhage. The other differential diagnosis would be hemangioma of the glans penis.        (CORP SPONG= corpus spongiosum; CORP AV= corpus cavernosus; Dorsum= dorsal part of the penis). AVM and hemangioma of the glans penis are extremely and hardly any cases are reported in medical literature.

This calculus is launched at the distal end of the penile urethra (see ultrasound image of the calculus in the distal end of the penis). This patient complained of pain and difficulty in passing urine. Ultrasound image of penile urethral calculus is courtesy of Dr. Ravi Kadasne, MD, UAE.

Another example of penile fracture. Here again, there is rupture of the tunica albuginea and the corpus cavernosum. Ultrasound image is courtesy of Dr. Ravi Kadasne, MD, UAE.
