in this video we see the curvilinear scanner on an abdominal preset in approximately transverse to sagittal plane in the right upper quadrant in a patient presenting with right upper quadrant and epigastric pain and immediately we see the gallbladder come into view and as the scanner goes down along the gallbladder we see finding suspicious for an enlarged gallbladder thickening of the gallbladder wall and here is some pericholecystic fluid and as the scanner goes down towards the neck of the gallbladder there's an obvious gallstone as evidenced by this acoustic shadowing here with a bright circular structure and the shadowing behind it evident of a gallstone that likely is lodged in the neck of the gallbladder combined with a sonographic murphy sign these findings would be consistent with acute cholecystitis to confirm the transducer would be rotated to get a longitudinal view as well to really identify that gallstone in the neck of the gallbladder and see the full longitudinal aspect of the gallbladder
