Fig 4. Example of divergent findings in CDUS and CT.

While the main trunk of the portal vein was graded as ‘partial thrombosis’ by CDUS (A), since thrombotic material could be identified in the vessel lumen but a preserved portal venous flow signal was detectable, it was graded as ‘complete thrombosis’ by CT (B) and portography (C), as both showed thrombotic occlusion of the vessel lumen without contrast agent flow.
