With the increasing use of multidetector computed tomography and dynamic magnetic resonance imaging in evaluation of liver pathologies, a variety of vascular shunts are detected in the liver. These shunts can be related to tumors or they can be nonneoplastic. Identification of these shunts can help in diagnosing an underlying condition. We classify and describe a wide spectrum of intrahepatic vascular shunts with their key imaging features. After reviewing this article, the reader should have improved ability to detect and characterize intrahepatic vascular shunts, which will help in diagnosing an underlying condition and facilitate optimal patient care.

Sclerosing cholangitis can be idiopathic (primary) or secondary to an identifiable cause. Irrespective of cause, sclerosing cholangitis usually progresses to end-stage liver disease and warrants orthotopic liver transplantation. Recent studies provide new insights into the etiopathogenesis, natural history, diagnosis, and management of these different entities.
