Diagnostic Ultrasound - Abdomen and Pelvis

Multiple Hepatic Masses
Differential Diagnoses: Liver
(Left) Transverse US in a
patient with mucinous colon
cancer demonstrates multiple
large, hyperechoic metastases
ſt containing diffuse
echogenic foci st related to
subtle calcifications. Note
posterior acoustic shadowing
caused by the calcifications
. (Right) Transverse
abdominal US in a patient with
pancreatic cancer shows
numerous small, hypoechoic
metastases ſt throughout the
liver. The background liver is
echogenic from hepatic
steatosis, a common finding in
the setting of chemotherapy.
Hepatic Metastases
Hepatic Metastases
(Left) Abdominal grayscale US
shows multifocal fat
deposition, which appears as
geographic areas of increased
echogenicity ſt around the
portal vein . The lesion
shows no mass effect, and
vessels run through the lesion,
characteristic features of fatty
infiltration. (Right) Transverse
abdominal US shows 2 welldefined,
homogeneously
hyperechoic hemangiomas in
the right lobe of liver ſt.
Hepatic Steatosis (Multifocal)
Hepatic Hemangioma
(Left) Transverse abdominal
US shows 2 well-defined and
homogeneously hyperechoic
hemangiomas in the liver ſt.
Hemangiomas in the liver are
often multiple. (Right)
Transverse abdominal US in a
patient with lymphoma shows
multiple hypoechoic masses
ſt throughout the liver.
Lesions are markedly
hypoechoic, resulting in a
pseudocystic appearance
characteristic of lymphoma.
