Answer

Cerebral venous thrombosis involves the sagittal sinus in about 70% of cases; these patients present with signs and symptoms of increased intracranial pressure (ICP), such as headache and papilledema. Should the thrombus extend to the superficial cortical veins, then focal findings may be noted. In the appropriate setting with known risk factors, cerebral venous thrombosis must be considered, with the patient evaluated with MRI, MRA, or magnetic resonance venography (MRV).
