Diagnostic Ultrasound - Abdomen and Pelvis

Adrenal Carcinoma
(Left) Transverse
transabdominal color Doppler
ultrasound shows a large,
heterogeneous adrenal mass
with minimal peripheral
flow, central hypoechoic areas
of necrosis ſt, and scattered
calcification st. (Right)
Longitudinal decubitus
transabdominal ultrasound
demonstrates a large
nonspecific hypoechoic
adrenal mass . The upper
pole of the right kidney is
shown ſt.
Diagnoses: Adrenal Gland
(Left) Transverse
transabdominal ultrasound
shows a well-circumscribed,
solid isoechoic to liver adrenal
mass , which was proven to
be AC. The IVC st appeared
spared at this level. (Right)
Corresponding axial CECT
shows a large, hypodense right
adrenal mass with
infiltration of the surrounding
fat. Tumor extension into the
IVC is difficult to see on the
CT. The upper pole of the right
kidney is shown .
(Left) Corresponding axial T2
FS MR better demonstrates
T2-hyperintense tumor
thrombus in an accessory
hepatic vein extending to the
IVC st. The mass shows
homogeneous T2 bright signal
as well. Surgery confirmed
invasion of segment VI of the
liver with tumor thrombus
reaching the IVC. (Right)
Postoperative, follow-up axial
PET/CT performed 5 months
later shows a new
metabolically active mass
in the surgical bed compatible
with recurrent disease. Note
the surgical clips st.
