Cortical vein thrombosis with no sinus involvement has seldom been reported. Clinical diagnosis is difficult and may be overlooked. We describe 4 female patients wjth isolated cortical vein thrombosis. All patients were on low oestrogen oral contraceptives treatment. Major neurological symptoms were focal or generalized seizures, aphasia, hemiparesis in the absence of signs of intracranial hypertension. CT showed an ischémie lesion in 3 cases, one of which with hemorrhagic component, and all the lesions did not correspond to a known arterial territory. In 2 cases conventional angiography documented a marked circulatory slowing in cortical veins, without arterial occlusion, suggesting a venous thrombosis, in the other 2 MRI documented clearly a defect .of cortical veins. Anticoagulant therapy was used .'in all patients. Final outcome was favourable in all patients with complete recovery in 3 cases and minimal neurological sequelae in the other 1.
