Patient with acute cholecystitis. Note here the stones layering in the dependent portion of the gallbladder (red arrows) with the posterior dark shadowing dark shadowing (blue arrows)
With gallbladder dissension (>4cm) in the transverse orientation.
And gallbladder wall thickening (>3mm)
And even a small amount of pericholecystic fluid.
Take home points: 1. Don't forget to consider the gallbladder in patients with epig pain and non-specific labs. 2. Cholecystitis is a clinical dx with sono findings (stones + wall thick, biliary dissension, PCF, sono-murphy sign).
Take home points 2/2: 3. If pt condition changes or doesn't improve - don't be afraid to re-image - perhaps a different way.
