Diagnostic Ultrasound - Abdomen and Pelvis

Focal Testicular Mass
Differential Diagnoses: Scrotum
(Left) Sagittal power Doppler
ultrasound of the right testis
in an 18-year-old man shows a
focal wedge-shaped
hypoechoic region with
absent vascularity consistent
with segmental infarct in the
presence of prior history of
torsion. (Right) Sagittal color
Doppler ultrasound of the
right testis in a young man
after trauma shows a focal
avascular heterogeneous mass
. Follow-up images
demonstrated resolution
consistent with a focal
hematoma.
Testicular Torsion/Infarction
Testicular Hematoma
(Left) Transverse color
Doppler ultrasound of the
right testis in a young man
with acute onset pain without
preceding history of trauma
shows a heterogeneous
avascular mass , which was
confirmed to be a
spontaneous testicular
hemorrhage. (Right)
Transverse color Doppler
ultrasound in a 23-year-old
man with fever and scrotal
pain, shows a hypoechoic
avascular area in the testis,
confirmed to be a testicular
abscess.
Testicular Hematoma
Testicular Abscess
(Left) Sagittal color Doppler
ultrasound of the right testis
in a 65-year-old man with
scrotal mass shows a focal
hypoechoic mass with
increased vascularity, which
was confirmed to be
lymphoma. (Right) Sagittal
color Doppler ultrasound of
the right testis in a 45-year-old
man with acute lymphoblastic
leukemia shows a
hypervascular focal
hypoechoic mass confirmed
