Pancreas poorly visualised due to overlying bowel gas. Two mobile gallstones identified measuring 1.5 cm and 1.3 cm. The gallbladder wall is thickened up to 6 mm and there is mild hypervascularity and trace pericholecystic fluid. The gallbladder is focally tender while examination. The extrahepatic biliary tree is mildly dilated with the mid common bile duct measuring 10 mm. No choledocholithiasis seen. The liver is of normal size and has a smooth contour. Mild increased echogenicity of the liver suggesting mild fatty infiltration. No focal hepatic lesion identified although the entirety of the liver was not able to be visualised. Normal main portal vein diameter and flow. Right kidney measures 10.6 cm in bipolar length and the left measures 11.7 cm. Normal cortical thickness. No hydronephrosis or focal renal lesion. Spleen is not enlarged. No ascites.
Conclusion: Tender gallbladder containing mobile stones with mildly thickened and hyperemic wall suggestive of acute cholecystitis in this clinical setting. The common bile duct is mildly dilated up to 10 mm without an obstructing stone or lesion seen.
