Diagnostic Ultrasound - Abdomen and Pelvis

Ascending Cholangitis
(Left) Longitudinal abdominal
US in a patient with severe
cholangitis shows a markedly
dilated common bile duct
and right intrahepatic duct ſt,
containing layering debris st
due to biliary stasis. (Right)
Transverse abdominal US in
the same patient with
cholangitis shows amorphous
echogenic material st within
the dilated common hepatic
duct ſt, which represents a
combination of sludge and
pus. Small right pleural
effusion and atelectatic
lung is likely reactive.
Diagnoses: Biliary System
(Left) Transverse abdominal
US in a patient with
cholangitis shows mild to
moderate ductal dilatation ſt
and duct wall thickening of
the left intrahepatic ducts.
(Right) Transverse abdominal
color Doppler US in the same
patient with cholangitis shows
no color flow in the dilatated
left intrahepatic ducts ſt.
Color Doppler US confirms
that these lesions are dilated
bile ducts rather than hepatic
vessels.
(Left) Transverse abdominal
US in a patient with
cholangitis shows wall
thickening of the common bile
duct without luminal
distension. (Right) Transverse
abdominal color Doppler US in
the same patient with
cholangitis shows wall
thickening of the common bile
duct without luminal
dilatation . Color Doppler
US confirms that this lesion is
the bile duct rather than a
hepatic vessel.
