Diagnostic Ultrasound - Abdomen and Pelvis

Gonadal Stromal Tumors, Testis
Diagnoses: Scrotum
(Left) Sagittal grayscale
ultrasound of the right testis
in a 33-year-old man
demonstrates a well-defined,
hypoechoic, solid mass .
Pathology confirmed it to be a
Leydig cell tumor. (Right)
Sagittal grayscale ultrasound
of the right testis in a young
male demonstrates a solid
cystic mass with some
echogenic areas with
calcification ſt. Pathology
confirmed it to be a Sertoli cell
tumor.
(Left) Transverse color
Doppler ultrasound of the
right testis in a 16-year-old
male demonstrates a welldefined,
hypoechoic, solid
mass with minimal internal
vascularity. Pathology
confirmed it to be a benign sex
cord stromal tumor
(unclassified type). (Right)
Sagittal color Doppler
ultrasound of the testicular
mass shows no internal
vascularity. Pathology
confirmed it to be an adult
granulosa cell tumor.
(Left) Transverse grayscale
ultrasound of the testis in a
12-year-old boy demonstrates
a well-defined,
heterogeneous, hypoechoic,
solid mass . (Right)
Corresponding transverse
color Doppler ultrasound of
the testis demonstrates
internal vascularity in this
well-defined, heterogeneous,
hypoechoic, solid mass .
Pathology confirmed a Leydig
cell tumor.
