Clinical Case of Idiopathic Deep Cerebral Venous Thrombosis

Abstract

Cerebral venous thrombosis (CVT), albeit a serious medical condition, is a rare cause of cerebral ischemia, with a great potential for
morbi-mortality. It´s associated with infection, hormonal causes,
hypercoagulable states, dehydration, oral contraceptives, malignancies and others. Clinically, CVT has a wide spectrum of clinical
presentations. Headache is the most common manifestation. Diagnosis is made by imaging studies. The authors present a case
of a 79-year old woman suffering from headache and decreased
level of consciousness for one day. Physical examination revealed
a sleepy patient with a left hemiparesis. Head computed tomography revealed acute thrombosis of the deep venous system. The
patient was treated with subcutaneous enoxaparin, with later introduction of warfarin. Extensive search of the possible causes of
thrombosis was negative, considered therefore as idiopathic CVT
