What is the cause of this patient's right upper quadrant pain?
What are the ultrasound findings for the diagnosis of acute cholecystitis?
Positive Murphy's sign and cholelithiasis are the most sensitive. Gallbladder wall thickening and pericholecystic fluid are secondary signs.
The gallbladder contains numerous small stones. Gallbladder wall is minimally thickened at 3 mm and there is a very small amount of fluid adjacent to the gallbladder in the gallbladder fossa.
The patient had mild but definitely localised maximal tenderness over the gallbladder.
The findings are those of acute calculous cholecystitis.
