Diagnostic Ultrasound - Abdomen and Pelvis

Diffuse Gallbladder Wall Thickening
Differential Diagnoses: Biliary System
(Left) Longitudinal oblique
ultrasound in gangrenous
acute calculous cholecystitis
shows a markedly abnormal
gallbladder with shadowing
stones . There is asymmetric
wall thickening with
intramural fluid collections st
and focal thinning of the wall
at the fundus ſt. (Right)
Transverse ultrasound in a
patient with acute hepatitis
and fulminant liver failure
shows that the gallbladder
wall is circumferentially
thickened st with striations.
Ascites is noted.
Acute Calculous Cholecystitis
Acute Hepatitis
(Left) Longitudinal ultrasound
shows the gallbladder in a
patient with perforated acute
calculous cholecystitis. The
gallbladder wall is
asymmetrically thickened st
and there is intraluminal
debris with linear membranes
. (Right) Axial CECT of the
same patient shows multiple
calcified gallstones in an
abscess cavity st outside the
perforated gallbladder .
Acute Calculous Cholecystitis
Acute Calculous Cholecystitis
(Left) Longitudinal ultrasound
in a patient with
adenomyomatosis shows
diffuse thickening of the
gallbladder wall ſt with
several tiny focal polypoid
lesions . (Right)
Longitudinal ultrasound in a
patient with segmental
adenomyomatosis shows
diffuse thickening of the
gallbladder wall in the fundus
ſt with multiple small,
echogenic foci. There is a
transition zone st (waisting)
in the body with normal wall
thickness in the neck .
