Testicular volume is approximately 1–2 cm3
before
the age of 12 years and reaches 4 cm3
in pubertal
males. In the peripubertal period a difference of 3 mm
in anteroposterior diameter is significant. Testicular
size determination specially important at suspicious
to varicocele, testicular atrophy and acute scrotum.
Processus Vaginalis is outpouching of the parietal
peritoneum, through which the testis descends
from the abdomen to the scrotum between the 7th
and 9th months of fetal life. Failure of the testis to
descend and patency or anomalous closure of the
processus vaginalis result in the following conditions:
cryptorchidism, inguinoscrotal hernia, and hydrocele.
Hydrocele is an abnormal collection of fluid between
the visceral and parietal layers of the tunica vaginalis
and/or along the spermatic cord. In the normal
scrotum, 1–2 mL of serous fluid may be observed in
the potential tunica vaginalis cavity and should not be
mistaken for hydrocele.
Virtually all hydroceles are congenital in neonates
and infants and associated with a patent processus
vaginalis, which allows peritoneal fluid to enter the
scrotal sac.
In older children and adolescents, hydroceles are
usually acquired and are the result of an inflammatory
process, testicular torsion, trauma, or a tumor.
Acute Scrotum refers to a clinical picture of suddenonset scrotal pain, redness, and swelling and most
frequently caused by :acute epididymo-orchitis,
testicular torsion and or torsion of the testicular
appendages.
Testicular torsion occurs when an abnormally mobile
testis twists on the spermatic cord, obstructing its
blood supply (first venous and later arterial flow
obstruction) and the ischemia can lead to testicular
necrosis if not corrected within 5-6 hours of the onset
of pain. The testis is usually elevated as a result of the
torsion and the shortening of the cord itself and may
be in a transverse lie.
Testicular Microlithiasis is usually an incidental
finding and at this condition, calcifications are seen
as bright, nonshadowing hyperechoic foci (five or
more on any single view) within testis parenchyma
that tend to be uniform in size in each patient and
are distributed in a diffuse pattern or in peripheral
clusters. |
