Diagnostic Ultrasound - Abdomen and Pelvis

Hepatic Metastases
(Left) Transverse abdominal
grayscale ultrasound in a
patient with diffuse hepatic
metastases demonstrates a
markedly heterogeneous
appearance of the liver with
numerous refractive shadows
ſt caused by underlying
isoechoic metastases. Note
distortion of the portal veins
by mass effect . (Right)
T1WI C+ FS MR in the same
patient demonstrates that a
heterogeneous liver
appearance on ultrasound is
due to numerous masses ſt
virtually replacing the entire
liver parenchyma.
Diagnoses: Liver
(Left) Transverse abdominal
grayscale ultrasound in a
patient with carcinoid tumor
shows a round,
homogeneously hyperechoic
metastasis in the right lobe of
liver ſt. (Right) Longitudinal
abdominal grayscale
ultrasound in a patient with
pancreatic cancer shows
multiple small, hypoechoic
metastases ſt in a
background of underlying
hepatic steatosis.
(Left) Transverse abdominal
grayscale ultrasound in a
different patient with
pancreatic cancer shows
numerous small, hypoechoic
metastases ſt throughout the
liver. Notice the background
liver is echogenic from hepatic
steatosis, a common finding in
the setting of chemotherapy.
(Right) Portal venous phase
axial CECT in the same patient
with pancreatic cancer shows
numerous hypodense
metastatic nodules ſt
scattered throughout the liver.
