I had a CT scan of the abdomen after receiving an abnormal ultrasound with the following impression: Small area of calcific density noted in the region of the medial aspect fo the second portion of the duedenum. This is in the vicinity of the sphincter of Oddi. Thi could represent some calcification in the wall of the second portion of he duedenum, but coul also represent a small partially stone lodged at the sphincter of Oddi, but note is made that there is very little dilatation of the common bile duct or hepatic ducts. Thank you
Dear madam, I think that everything is said. It can be only calcification which means nothing. But it can also be a stone.  You didn't mentioned the exact symptoms which led you to these diagnostic tests, but if it is a stone lodged in sphincter of Odd you would have typical biliary comics or even jaundice from time to time. So I recommend you if u have these symptoms u should do cholecystectomy, if not u can do i too, or you can wait for symptoms to appear. Dilatation of duct goes with biliary obstruction due to stones or tumors. Wish you good health.
