Cerebral venous thrombosis is caused by thrombosis of cerebral veins and venous sinuses. Headache, epileptic seizures and focal deficit are the most common symptoms. In severe cases, intracranial hypertension or coma may be present. The diagnosis is based on finding on magnetic resonance imaging or computer tomography because both modalities can visualize both brain parenchyma and cerebral venous system. Specific treatment consists of anticoagulation with unfractionated heparin or low molecular weight heparin. Thrombolysis is a perspective therapy because thrombolytics can recanalize venous occlusion. Symptomatic treatment includes management of intracranial hypertension, agitation and epileptic seizures.
