Scrotum Ultrasound Images
3-5 x 2-4 x 3 cm
Testis measures
ductus epididymis
The duct in the epididymis is known as
spermatic cord
The pampiniform plexus exits from mediastinum testis and then heads to the?
rete testis in mediastinum
Tubules converge at apex of each lobule and anastomose to form
membranous sac around the testicle
Tunica vaginalis
visceral and parietal
Tunica vaginalis TWO LAYERS
pampinform plexus
Venous drainage of the scrotum occurs through
covers testis and epididymis
Visceral layer of the tunica vaginalis covers
spermatic cord
A
transmediastinal artery
A
centripetal arteries
B
capsular artery
C
epididymis
Contains 10 to 15 efferent ductules from rete testis, which converge to form single duct in body and tail
Homogenous echotexture, uniformly distributed medium level echoes
Describe a healthy testes in US terms
homogenous echotexture, uniformly distributed medium level echoes
Describe sonographically healthy testes
testicular to capsular to centripetal to recurrent rami
Describe the vascular artery branching
seminiferous tubules
Each testis divided into > 250 to 400 conical lobules containing
left renal vein
Left testicular vein drains into the?
hyperechoic isoechoic hypoechoic anechoic
Name left to right
isoechoic or hypoechoic compared with testis, echo texture coarser
Normal epididymis sonographically
covers and lines the scrotal sac
Parietal layer of the tunica vaginalis covers
mediastinum
Posterior aspect of tunica albuginea reflects into testis to form vertical septum
inferior vena cava
Right testicular vein drains into the?
ductus epididymis
What becomes the vas deferens and continues in spermatic cord.
tunica albuginea
What covers the testicle
testes appear as smooth, medium gray structures with fine echo texture
What do testes look like sonographically
vas deferens, testicular arteries, venous pampiniform plexus
What does the spermatic cord contain?
rete testis
What drains into head of epididymis through efferent ductules?
appendix of the testes
What is an embryological remnant of the testes
effurent ductules and rete testes
What is found in the mediastinum
mediastinum
What is not covered by the tunica albuginea
a fibrous connective tissue which encloses the rete testis
What is the mediastinum
10 to 14 MHz
What kind of transducer is used to scan testes
tunica albuginea
What projects inward to form septa and divides into lobules
vas deferens
What transports sperm from the epididymis to the urethra
abdominal aorta
Where do right and left testicular arteries arise from
mediastinum testes
a mass of connective tissue continuous with the tunica albuginea
testicular artery capsular centripetal recurrent rami
explain arterial blood flow
3-5 cm
how long is the testicle
testicular vein
pampinform plexus becomes what?
rare condition, ectopic testicle that cannot be manipulated, typically rests superficial to inguinal pouch.
testicular ectopia
testis epididymis vas deferens spermatic cord
what are the 4 major components of the scrotal sac
protects the testicles from temperature changes
what is the main job of the scrotum
fascia
what is the spermatic cord made of?/
