Cytomegalovirus-associated cerebral sinus vein thrombosis.

Cytomegalovirus (CMV)-associated thrombosis has been reported many times in the medical literature, and most patients had deep vein thrombosis and/or pulmonary embolism. CMV-associated cerebral sinus vein thrombosis has been reported only twice. We present an immunocompetent patient with CMV-associated cerebral sinus vein thrombosis and no other thrombosis risk factors. This is another example of the pro-thrombotic features of CMV. Physicians should be alert for symptoms and signs of acute CMV infection in patients with thrombosis.
