Diagnostic Ultrasound - Abdomen and Pelvis

Diffuse Testicular Enlargement
Testicular Torsion/Infarction
Testicular Carcinoma
(Left) Transverse color
Doppler US of bilateral testes
demonstrates an enlarged
heterogeneous right testis
with complete absence of
blood flow suggestive of acute
testicular torsion with
infarction. (Right) Sagittal
grayscale US of the right testis
demonstrates an enlarged
heterogeneous testis with
multiple hypoechoic masses in
the background of testicular
microlithiasis pathologically
confirmed to be testicular
seminoma.
Differential Diagnoses: Scrotum
Scrotal Trauma
Testicular Lymphoma
(Left) Sagittal grayscale US of
the left testis in a young male
recently involved in a motor
vehicle accident demonstrates
an enlarged heterogeneous
irregular testis with
contour abnormality st
suggestive of testicular
rupture. (Right) Sagittal
grayscale US of the left testis
demonstrates an enlarged
heterogeneous testis with a
large hypoechoic mass that
was pathologically confirmed
to be testicular lymphoma.
Testicular Metastases
Testicular Cyst
(Left) Transverse grayscale US
of the right testis in a young
male with history of
rhabdomyosarcoma
demonstrates an enlarged
testis with multiple
hypoechoic masses that
were pathologically confirmed
to be metastases from
rhabdomyosarcoma. (Right)
Transverse color Doppler US
demonstrates an enlarged left
testis with multiple anechoic
structures without internal
blood flow or solid
components, compatible with
testicular cysts.
