Reason: Evaluate for cholecystitis/docholithiasis History: Abdominal pain. Pancreatic and cbd dilation on ct. Possible ampullary cancer vs impacted gallstone. BILIARY TRACT: There is no evidence of cholelithiasis, gallbladder wall thickening, or pericholecystic fluid. The sonographic Murphy's sign is negative. No intrahepatic or extrahepatic biliary ductal dilatation is present. The common bile duct measures 5 mm in diameter. No shadowing choledocholithiasis identified.PANCREAS: Pancreas is largely obscured. There appears to be mild prominence of the proximal pancreatic duct as seen on recent CT.
No evidence of acute cholecystitis or significant biliary ductal dilatation. Mildly prominent proximal pancreatic duct as seen on same-day CT. If there is continued clinical concern for an ampullary process or choledocholithiasis, MRCP can be considered as clinically warranted.
