Diagnostic Ultrasound - Abdomen and Pelvis

Hepatomegaly
Differential Diagnoses: Liver
(Left) Longitudinal abdominal
ultrasound in a patient with
severe hepatic steatosis shows
an enlarged liver measuring 21
cm in length, diffusely
echogenic liver ſt compared
to the right kidney st, and
marked attenuation of the US
beam which results in poor
visualization of the diaphragm
. (Right) Longitudinal
abdominal ultrasound in a
patient who presented with
acute liver failure from acute
alcoholic hepatitis shows a
markedly enlarged liver
extending well below the
inferior renal margin.
Fatty Liver
Steatohepatitis
(Left) Transverse abdominal
ultrasound in a patient with
venoocclusive disease shows a
markedly enlarged and
edematous liver resulting in
narrowed hepatic veins st and
small-caliber inferior vena
cava ſt. A small right pleural
effusion is also evident .
(Right) Longitudinal
abdominal ultrasound in a
patient with venoocclusive
disease shows marked
hepatomegaly with
craniocaudal length of the
liver measuring 22.6 cm .
Liver extension well beyond
the edge of the kidney is
indicative of hepatomegaly.
Venoocclusive Disease
Venoocclusive Disease
(Left) Transverse grayscale
ultrasound of the liver shows a
markedly heterogeneous and
enlarged liver with multiple
refractive shadows ſt caused
by diffuse, infiltrative HCC.
Focal echogenic lesion was
shown to be a fat-containing
focus of HCC. (Right)
Transverse abdominal color
Doppler ultrasound shows the
right portal vein filled with
echogenic material ,
consistent with portal vein
tumor thrombosis. Underlying
liver is markedly
heterogeneous because of
diffuse HCC.
