Hi Group 4:

In patients with jaundice. one must try to distinguish between hepatic and biliary disease. In the patient with suspected biliary obstruction, without the pain typically associated with gallstones, one should be suspicious of malignancy or strictures. In the case presented, the clinical picture is worrisome for a malignant cause of biliary obstruction. such as pancreatic cancer. This drives us to want to "see" what is happening. Hence your choices of ultrasound and CT scans are right on the money!

Nicely done!
