[Cerebral venous thrombosis presenting as subarachnoid hemorrhage].

Headache of subacute onset, associated with other signs of increased intracranial pressure, represents the most frequent symptom of cerebral thrombophlebitis. We report a case of subarachnoid hemorrhage as a rare presentation of cerebral thrombophlebitis. Unfractionated intravenous heparin treatment resulted in resolution of subarachnoid hemorrhage on control brain CT scan and quick clinical recovery.
