Diagnostic Ultrasound - Abdomen and Pelvis

Echogenic Bile
(Left) Transverse ultrasound
shows sludge filling the
gallbladder ſt. The sludge is
isoechoic to the liver, referred
to as "hepatization." (Right)
Longitudinal left lateral
decubitus ultrasound shows
dependent sludge with a
polypoid appearance st. The
gallbladder wall is normal ſt.
Diagnoses: Biliary System
(Left) Longitudinal ultrasound
shows the gallbladder
containing tumefactive sludge
ſt, which does not shadow.
(Right) Longitudinal
ultrasound of the gallbladder
in a decubitus position shows
multiple bright, floating
intraluminal echoes ſt, which
were mobile. Note the poorly
distended gallbladder with
apparent wall thickening st.
(Left) Longitudinal ultrasound
in a decubitus position shows
dependent echogenic sludge
ſt, which has aggregated into
a clump. (Right) Longitudinal
ultrasound of the same
patient in decubitus position
shows dependent echogenic
sludge demonstrating
twinkling artifact ſt.
