Diagnostic Ultrasound - Abdomen and Pelvis

Focal Extratesticular Mass
Inguinal Hernia
Inguinal Hernia
(Left) Oblique ultrasound
shows an inguinoscrotal
hernia, containing small bowel
loops ſt, and mesentery .
Note the bowel wall (gut
signature), which distinguishes
this from a cord or epididymal
mass. Note the fluid in the
hernia sac st. (Right)
Longitudinal ultrasound shows
an ill-defined, lobulated,
echogenic st structure
herniating into the scrotum
, features suggestive of an
omentocele.
Differential Diagnoses: Scrotum
Fatty Deposition
Fatty Deposition
(Left) Longitudinal ultrasound
shows an ill-defined
hyperechoic structure ſt
surrounding the epididymis st.
This "pseudomass" is due to
the deposition of fat. (Right)
Transverse ultrasound shows
an ill-defined, hyperechoic
structure ſt in the region of
the body and head of the
epididymis. No obvious
discrete mass is identifiable.
This "pseudomass" is likely due
to the deposition of fat. Parts
of epididymis can be seen as
small hypoechoic areas
within the "pseudomass." Note
the normal testis st.
Encysted Hydrocele of Cord
Encysted Hydrocele of Cord
(Left) Longitudinal ultrasound
shows an elongated anechoic
fluid collection ſt within
layers of the distal spermatic
cord in the inguinoscrotal
region. Note the splayed
layers st of the proximal
spermatic cord, features
suggestive of an encysted
hydrocele of the spermatic
cord. (Right) Transverse
ultrasound shows a chronic,
fluid collection ſt with
multiple fine septations in
the inguinoscrotal region
representing an encysted
hydrocele of the spermatic
cord.
