### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
Distended gallbladder. Wall appears to show some areas of increased echogenicity which could represent cholesterol deposits. Calcification is not excluded although there does not appear to be shadowing. Polyps are felt to be less likely.  The largest of these measures up to 10mm.  Common bile duct diameter is very distended at 9.7mm.  No intrahepatic biliary ductal dialation demonstrated.  These are notes from my recent abdominal ultrasound...Thoughts please.

### output:

Hello there !  Studied your report of GB scan. Your CBD is distended for sure. The maximum limit is 6 to 7 mm. these areas of increased echogenicity can not be associated with anything unless correlated with your thorough history and physical exam. Cause it changes with age and anything starting from obesity to fatty liver to Lipoproteins or liver metabolism or some obstruction in common bile duct. Usually the duct gets distended from obstruction the two main reasons for which are Alcohol and Stones. So I suspect it because of alcohol cause alcohol gets metabolized to fats and cholesterol and as your scan also narrated the correlation, but I am afraid that little of history is all I can get to or speculate. But your CBD is for sure dilated. Now If there are pains and associations like nausea vomiting fever etc., i would arise to further investigated the ct scan abdomen and pelvis, Pancreatic profile assessment to rule out pancreatitis or malignancy that is Serum amylase, urinary amylase, amylase to lipase ratio, CA 19-9, I would also advise THC(trans hepatic cholangiographic) Or MRCP(magnetic resonance cholangiopancreatography) or ERCP(Endoscopic retrograde cholangiopancreatography) and some Magazine DiAtrazoate or barium Meals X-rays. But as I said clinical correlation is the main platform to proceed not just one U/S scan report. You should have stated Your little history and things could have been more in your favor. Anyhow I have managed to help you out the best I could. If you need me don't forget that I am here for you. You can contact me any time any way you want.
