A 35-year-old men with a medical history of myocardial infarction, presenting with fever, general malaise and vague abdominal discomfort, was diagnosed with a portomesenteric venous thrombosis and acute cytomegalovirus (CMV) infection. Thrombophilia screening resulted in detection of heterozygosity for factor II G20210A gene mutation. Low molecular weight heparin in therapeutic dose was started, followed by disappearance of thrombus on imaging CT two months after diagnosis. The multifactorial origin of portal thrombosis and the importance of awareness of the link between CMV infection and an increased risk of thrombosis is emphasized with this case and review of the literature. Identifying CMV infection as a trigger for thrombosis can help to avoid extended anticoagulation. Acute non-cirrhotic PVT is a rare but probably underestimated condition as symptoms may be discrete or non-specific. The origin of portal thrombosis is frequently multifactorial. Recent literature has emphasized the increasing prevalence of CMV-induced PVT in immunocompetent patients. The multifactorial origin of portal thrombosis and the importance of awareness of the link between CMV infection and an increased risk of thrombosis is emphasized with this review of the literature and included case. Identifying CMV infection as a trigger for thrombosis can help to avoid extended anticoagulation. (Acta gastroenterol. belg., 2018, 81, 318- 322).
