Diagnostic Ultrasound - Abdomen and Pelvis

Amebic Hepatic Abscess
(Left) Longitudinal ultrasound
of the right lobe of the liver
demonstrates a welldemarcated
and capsulated
hypoechoic amebic abscess ſt
with internal echoes st
indicating debris. Note the
mild posterior acoustic
enhancement and small
right pleural effusion .
(Right) Power Doppler
ultrasound performed in the
same patient shows no
detectable internal vascularity
within the amebic abscess ſt.
Diagnoses: Liver
(Left) Sagittal ultrasound
shows a large, round
hypoechoic amebic abscess in
the right lobe of liver ſt
abutting the liver capsule .
Internal contents are
hypoechoic with
heterogeneously echogenic
scattered foci st. Also note
the posterior acoustic
enhancement . (Right)
Transverse grayscale
ultrasound in the same patient
shows a hypoechoic mass ſt
with internal heterogeneous
echogenic contents st and
hypoechoic halo .
(Left) Transverse grayscale
ultrasound of the right lobe of
the liver demonstrates a
round, well-demarcated,
hypoechoic amebic abscess ſt
with low-level internal echoes
st. Note how the abscess
abuts the liver capsule and
diaphragm . (Right)
Transverse color Doppler
ultrasound performed in the
same patient shows no
detectable internal vascularity
in the mass ſt.
