Comparison made with previous study. Note cholecystectomy clips. 10mm ovoid filling defect seen within the proximal common bile duct at the level of the cystic duct is consistent with an intraductal calculus. Mild intrahepatic duct dilatation . The bile duct distal to the calculus is however enlarged measuring 14mm, with the possibility of a 2nd distal CBD calculus. Contrast is demonstrated passing into the duodenum. Note is made of the previous US report of a possible pancreatic head lesion, and although no definite lesion is identified in this study, a dedicated pancreas examination has not been performed.
Visualised abdominal viscera are unremarkable.
Bibasal atelectasis with dependent changes.
Conclusion: 10mm proximal common bile duct calculus and possible 2nd distal CBD calculus, but without evidence of complete obstruction.
