Diagnostic Ultrasound - Abdomen and Pelvis

Testicular Microlithiasis
Diagnoses: Scrotum
(Left) Transverse grayscale
ultrasound of the bilateral
testes demonstrates an
atrophic left testis with
bilateral microlithiasis ſt.
Annual screening ultrasound is
indicated due to increased risk
for cancer in an atrophic
testicle with microlithiasis.
(Right) Transverse grayscale
ultrasound demonstrates the
left undescended testis in
the left inguinal canal with
microlithiasis st. This needs to
be annually screened by
ultrasound due to increased
risk for cancer.
(Left) Transverse grayscale
ultrasound of the scrotum
demonstrates a single leftsided
testis with
microlithiasis st. The patient
had a history of right
orchiectomy for germ cell
tumor and was being screened
annually for increased risk of
cancer. (Right) Sagittal
grayscale ultrasound shows
the left testis with
macrocalcifications st and a
large, hypoechoic mass
confirmed to be a seminoma.
(Left) Sagittal grayscale
ultrasound of the right testis
demonstrates scattered micro-
and macrocalcifications .
The left testis was normal
without microlithiasis. The
patient was followed up with
an annual ultrasound. (Right)
Sagittal grayscale ultrasound
follow-up in the same patient
after 3 years demonstrated
development of a large
heterogeneous mass .
Pathology confirmed a mixed
germ cell tumor (95%
embryonal, 5% teratoma).
