Diagnostic Ultrasound - Abdomen and Pelvis

Decreased Testicular Size
Testicular Infarction
Testicular Infarction
(Left) Sagittal grayscale US of
the right scrotum in a 42-yearold
man with recent history of
right inguinal hernia surgery
who presented with worsening
right scrotal pain is shown.
Color Doppler US
demonstrates complete
absence of flow in the testis
and an edematous cord .
(Right) Transverse grayscale
ultrasound image of bilateral
testes shows an atrophic right
testis with a striated pattern
. Patient had a remote
history of right-sided
epididymoorchitis.
Differential Diagnoses: Scrotum
Chronic Mass Effect
Chronic Mass Effect
(Left) Sagittal grayscale
ultrasound of the left scrotum
shows a small left testis
pushed to 1 side by the large
echogenic "mass" confirmed to
be an omental inguinal hernia
. (Right) Sagittal color
Doppler ultrasound images of
bilateral testis shows an
atrophic right testis ,
secondary to a large hydrocele
.
Testicular Infarction
Testicular Infarction
(Left) Transverse color
Doppler view of bilateral
testicles shows that the left
testis is atrophic with
reduced vascularity. The
patient had a prior history of
mumps orchitis. (Right)
Follow-up power Doppler
image of a 50-year-old patient
with prior history of orchitis
demonstrates a severely
atrophic and avascular left
testis , consistent with
infarction, a rare complication
of orchitis.
