Abstract
Dissecting aneurysms of intracranial artery often arise in the posterior circulation, but those in the anterior circulation are rare, presenting with hemorrhagic event. So, we report an unusual case of isolated dissecting aneurysm of the pericallosal artery presenting with spontaneous subarachnoid hemorrhage. A 46-year-old hypertensive woman presented with severe headache and intense nuchal rigidity after onset of two days. Computed tomography (CT) brain scan revealed a subarachnoid hemorrhage and an interhemispheric hematoma. This was due to dissecting aneurysm of left pericallosal artery on conventional cerebral angiography. Total occlusion of the dissecting aneurysm was performed with five Guglielmi detachable coils, with no apparent procedure-related complications. Endovascular treatment by aneurysm and parent artery occlusion is a relatively reliable alternative to surgery for isolated dissecting aneurysm of pericallosal artery.
Key Words: Dissecting aneurysm; Pericallosal artery; Subarachnoid hemorrhage; Endovascular treatment
