Idiopathic scrotal edema:

 

edema of scrotum in a child     idiopathic scrotal edema

ultrasound images of scrotal edema     edema of the prepuce

Sonography of the scrotum was done in this child who had acute swelling of the scrotum and penis. Ultrasound images reveal 1) thickening (11mm.) of the scrotal and penile skin and subcutaneous tissue and 2) marked hyperemia of the scrotum as well as the prepuce. The testes show normal appearance on sonography. These ultrasound and color doppler images are diagnostic of idiopathic scrotal edema. Images taken using a Nemio XG color doppler machine, by Joe Antony, MD.

Torsion of testes:

 

Ultrasound images showing torsed left testes:

the left spermatic cord is twisted     swollen and edematous left testes

normal right spermatic cord     snail sign of testicular torsion

absent flow on color doppler in left testes     small hydrocele in torsion of left testes

ultrasound image of torsion testes     normal right testes

Testicular torsion occurs most commonly due to long spermatic cord. There are 2 types of torsion: extravaginal (usually in newborns) and intravaginal torsion (usually at puberty). In the ultrasound images above, the left testes appears swollen and mildly hypoechoic. A small left hydrocele is also present. On color doppler imaging, the left testes shows absence of blood flow. The "snail sign" is also seen in the left testes, caused by swollen testes (shell of snail) and twisted, bulky spermatic cord (body and head of snail). These ultrasound images suggest torsion of the left testes. The affected testes was removed and found to be gangrenous.

Testicular trauma (rupture of testes or fracture testes):

contusion of testes     hematocele

rupture of right testes     fracture of testes

edema of scrotum     normal left testes

multiple septae in hematocele     fracture of testes obvious

This 34 yr. old male patient had a severe blunt injury to the right scrotum 2 days prior to sonography. Ultrasound images of the scrotum reveal 1) a small hypoechoic fluid collection (hematocele)l in the right tunica vaginalis sac. .              

                                                   2) multiple septations within the Rt. tunica vaginalis sac

                                                   3) rupture of the tunica albuginea of the right testes

                                                   4) hypoechoic areas within the right testes s/o contusions

                                                   5) thickening of the scrotal wall (edema).

                                                  6) edematous and swollen right testes

The left testes appears normal. These ultrasound images suggest contusion and rutpture of the right testes with hematocele. These sonographic images were taken using a Pie scanner 100 Falco ultrasound machine, by Dr. Joe Antony, MD, India.

Ischemic orchitis:

ultrasound image showing ischemic orchitis      color doppler image of ischemic orchitis

This young male patient underwent hernia repair, following which he complained of pain and swelling of left scrotum. Sonography of the scrotum shows: 1) hypoechoic left testes 2) swelling of the left testes 3) absence of vascularity in left testes. These ultrasound and color doppler images suggest left ischemic orchitis. Ischemic orchitis is a known complication of herniorraphy. Ultrasound images courtesy of Dr. Ravi Kadasne, UAE.

Torsion of appendix testes with hydrocele:

appendix testes floating in fluid     right testes and epididymis with hydrocele

large hydrocele on right side     appendix testes seen well at upper pole

appendix testes in groove between the epididymis and testes     appendix testes shows echogenic outer rim

typical location of the appendix testes

This patient, a young adolescent male had selling, pain and mild tenderness of the right scrotum. High frequency ultrasound probe shows a large right hydrocele with clear fluid content surrounding the the right testes. The right testes and epididymis are well outlined by the anechoic fluid. Ultrasound images also show the appendix testes occupying the groove between the testes and epididymis on the upper pole. The testicular appendix shows echogenic rim with hypoechoic central part and no vascularity on color Doppler imaging (topmost image). These ultrasound findings suggest torsion of the right testes with hydrocele.

Epididymal abscess (bilateral abscess of epididymis):

Hypoechoic, swollen, tender epididymis:

Ultrasound image of left epididymis    the right epididymis is also swollen and hypoechoic

increased vascularity of the affected parts    Testes show hypoechoic areas

This male patient complained of pain and swelling of the scrotum. Sonography of the scrotum showed bilateral swollen epididymis. Ultrasound images of the epididymis showed them to be markedly hypoechoic (hyperemia with edema) and had increased vascularity (on Color Doppler imaging). The affected regions are mainly the body and tail of these structures. The testes also showed multiple small hypoechoic lesions (image on bottom right- arrowed), possibly due to obstructed seminiferous tubules (sperm granuloma formation). These ultrasound images suggest bilateral epididymal inflammation (epididymitis) with abscess formation. All images are courtesy of Dr. Ravi Kadasne, UAE. Images were taken using a Philips IU-22 ultrasound system.

Inguinal hernia:

ultrasound image showing the hernial sac    sonography right inguinal hernia

The above ultrasound images show herniated bowel showing peristalsis within the right scrotal sac. (T= right testis; H= herniated bowel). This is the typical finding in inguinal hernia. Inguinal hernias may be direct or indirect depending on the relation of the hernial sac with the inferior epigastric artery. Those that are medial to the inferior epigastric artery are direct while those lateral to the artery are said to be indirect. Ultrasound images are courtesy of Dr. Ravi Kadasne, UAE.

Strangulated inguinal hernia:

indirect inguinal hernia      strangulated bowel in inguinal hernia

3-D ultrasound strangulated inguinal hernia  

This male patient presented with severe pain and tenderness in the right inguinal region. On examination, there was a tender mass in the right inguinal area. Sonography of the inguinal mass showed a hypoechoic collection (the hernia sac with echogenic tissue- bowel loop) with a very neck. Color Doppler imaging of the mass showed absent flow in the structures within the sac (not shown here). These ultrasound images suggest strangulated right inguinal hernia. This was confirmed on surgery. The strangulated inguinal hernia contained an ischemic and edematous bowel loop. The image in bottom row shows 3-D visualization of the hernia.
