Diagnostic Ultrasound - Abdomen and Pelvis

Focal Extratesticular Mass
Liposarcoma of Spermatic Cord
Liposarcoma of Spermatic Cord
(Left) Proliferative fat within
the inguinal canal inferiorly
displaces the right testis st in
a patient with right inguinal
liposarcoma. (Right) CECT in
the same patient shows bulky
adipose tissue with soft tissue
elements in the upper
scrotum in this spermatic cord
liposarcoma.
Differential Diagnoses: Scrotum
Epididymal Rhabdomyosarcoma
Metastases
(Left) Longitudinal ultrasound
shows a large, heterogeneous,
paratesticular mass st
compressing the testis ſt. The
epididymis could not be seen
separately in this patient with
epididymal
rhabdomyosarcoma. (Right)
Oblique ultrasound shows a
small, well-defined,
hypoechoic lesion ſt within
the head of the epididymis in
this patient with known
disseminated malignancy. The
final diagnosis was epididymal
metastases.
Tuberculous Epididymitis
Tuberculous Epididymitis
(Left) Transverse ultrasound
shows an enlarged, lobulated,
epididymal head ſt. Note the
heterogeneous intrinsic echo
pattern st, features
suggestive of a chronic
granulomatous inflammatory
mass in this patient with
tuberculous epididymitis. Note
the normal testis . (Right)
Oblique ultrasound follow-up
performed 2 years later in the
same patient shows a welldeveloped
area of necrosis ſt
within the chronically
inflamed epididymal head st.
