Diagnostic Ultrasound - Abdomen and Pelvis

Testicular Germ Cell Tumors
(Left) Longitudinal grayscale
ultrasound of the testis in a
patient with a cystic teratoma
shows a complex
heterogeneous mass with
cystic areas ſt of varying sizes
and small echogenic foci .
(Right) Transverse color
Doppler ultrasound of both
testes in a side-by-side
configuration shows a rightsided
teratoma with cystic
spaces and associated
increased vascularity .
Diagnoses: Scrotum
(Left) Transverse color
Doppler ultrasound of the
testis demonstrates a poorly
defined hypoechoic mass
with internal vascularity. The
mass invades the tunica
albuginea ſt and involves the
scrotal wall. (Right)
Longitudinal grayscale
ultrasound of the testis shows
a heterogeneous well-defined
mass with cystic ſt as well as
hypoechoic areas .
Pathology revealed a mixed
germ cell tumor with
choriocarcinoma and mature
teratoma.
(Left) Longitudinal color
Doppler ultrasound of the
right testis with multifocal
seminoma shows multiple
hypoechoic masses with
background microlithiasis st,
predominantly peripheral
vascularity , and minimal
internal vascularity within the
hypoechoic masses. (Right)
Axial CECT of the mid
abdomen shows a
conglomerate of metastatic
paraaortic and retroperitoneal
low-density lymph nodes st in
a patient with testicular
cancer.
