Diagnostic Ultrasound - Abdomen and Pelvis

Hepatic Steatosis
(Left) Transverse abdominal
US in a patient with hepatic
steatosis shows a geographic
area of decreased
echogenicity, suggesting focal
fatty sparing ſt in the
posterior subcapsular portion
of segment 4 of liver, which is
drained by an aberrant right
gastric vein. (Right) Oblique
abdominal US shows a fanshaped
area of focal fat
deposition ſt as increased
echogenicity of the liver
anterior to the porta hepatis
.
Diagnoses: Liver
(Left) Oblique abdominal
grayscale US shows
geographic focal fatty
infiltration ſt as a wedgeshaped
area with increased
echogenicity extending up to
the subcapsular portion of
right lobe of liver. Note the
normal vessel coursing
through the area of fatty
infiltration. (Right) Color
Doppler US in the same
patient shows focal fatty
infiltration with a normal
hepatic vein st coursing
through the area without
displacement.
(Left) Longitudinal abdominal
US shows focal fatty sparing
at the gallbladder fossa as a
geographic area of decreased
echogenicity ſt. Liver
adjacent to the gallbladder
fossa is a typical location for
fatty sparing. (Right) Oblique
abdominal US in a patient with
acute alcoholic hepatitis
shows moderate steatosis as
diffusely increased
echogenicity of hepatic
parenchyma along with poorly
delineated intrahepatic
vascular margins st.
