Cerebral Sinus Vein Thrombosis following Sneezing: Case Report.

Cerebral sinus vein thrombosis (CVT) is a relatively rare neurovascular entity, usually associated with acquired or genetic hypercoagulable states, and in many cases it remains idiopathic. Trauma is also associated with CVT among patients with major head or neck trauma, including penetrating injuries. However, CVT associated with acceleration trauma has only been described in few cases so far. We present an unusual case of a 19-year-old woman with no past medical history, admitted with an extensive CVT following sneezing. A thorough investigation did not reveal any other potential etiology or risk factor other than estrogen-containing oral contraceptives. The patient was treated with anticoagulation and improved clinically with complete recanalization on follow-up imaging. This case suggests acceleration trauma may be a potential factor of risk for CVT.
