Asymptomatic superior mesenteric vein thrombosis as unusual complication of acute cytomegalovirus infection: a case report
2015
We describe a 39-year-old male who presented with a
feverof
unknown origin, the diagnostic work-up of which disclosed an acute cytomegalovirus (CMV) infection complicated by a partial
superior mesenteric vein(SMV)
thrombosis. Further investigations revealed the presence of
factor V Leiden mutation. Oral anticoagulant treatment with warfarin led to a complete recanalization of SMV two months after. A literature review on the association between CMV infection and portal system (PS)
thrombosisin immunocompetent patients was performed. We found that, in agreement with our case, in a minority of case reports patients did not complain of abdominal pain, but presented with a
mononucleosis-like syndrome with
malaiseand prolonged fever and displayed a variable elevation of aminotransferase levels. Interestingly, most of them exhibited a limited extension of
portal thrombosis. On the whole, these data suggest that PS
thrombosisduring acute CMV infection may be an underestimated complication.
