I would consider seeing a liver specialist if the bilirubin continues to rise. Diseases like primary biliary cirrhosis can present with abnormal liver function tests and itching. Further tests, like testing for the anti-mitochondrial antibody, can be considered.
An ultrasound should be considered in conjunction with the CT scan to rule out a bile duct leak.
If the GI system has been completely evaluated without a cause, hemolytic anemia can also lead to an elevation of bilirubin. Further blood tests, and a evaluation by a hematologist, can be considered if this is suspected.
Followup with your personal physician is essential.

Something is up with all that itching and the raised liver enzymes.
