Hello,
Thank you for the consult. 
Since I have only the patients CT results and some blood investigations with me, I will opine on them here.

From the CT report, there appears to be a swelling up of the entire biliary canal (which carries bile) till the end. The reason for the swell up seems to be due a small mass by the end of the canal. This happens to be near the pancreas where the canal ends. What kind of a mass, the extend, the cause etc cannot be made out in the CT. So the recommended approach would be a ECRP – another mode of detailed scanning where the ducts can be closely observed and a biopsy to be taken from the mass leasion. This will give further information into the swelling.

Blood test results show deranged liver function causing jaundice. The jaundice is obstructive type which correlates with the CT results.

I assume that the patient is already under medical care. She will need supportive care now and further imaging studies. Hope this helps.
