Introduction:
Subarachnoid hemorrhages caused by intracranial dissections are rare. The management of dissections in these cases not clear.
Methods:
Case report.
Results:
An 82-year-old woman presented with acute drowsiness and vomiting. CT scan demonstrated extensive subarachnoid hemorrhage and hydrocephalus that subsequently required placement of ventriculoperitoneal shunt. Angiography revealed extensive basilar artery dissection and no aneurysms. The dissection did not produce a critical stenosis and, taking into consideration that the patient had a previous occlusion of her distal left vertebral artery, it was decided to manage the patient conservatively. On a 3-month follow-up, the patient was free of recurrent events.
Conclusion:
Basilar artery dissection can present with subarachnoid hemorrhage. No guidelines are available for management of basilar artery dissections and treatment should be tailored to the individual patient.
