Cytomegalovirus-associated portal vein thrombosis in an immunocompetent patient: an underestimated complication.

We describe an immunocompetent adult with acute cytomegalovirus (CMV) infection complicated by extensive portal vein thrombosis. A literature review on the incidence, presentation, pathophysiology and management of CMV-associated thrombosis is included. Previously thought to be a rare complication, recent large case series and the present case reconfirm the increasing prevalence of CMV-associated thromboembolism in the immunocompetent adult.
