Abstract
|
|
|
|
Nonaneurysmal cortical subarachnoid hemorrhage (cSAH) is a rare condition associated with various etiologies. Given the association between carotid artery stenosis and cSAH, we report a case of a patient with hemorrhage associated with significant intracranial arterial stenosis. Furthermore, we discuss angiographic findings to support the relationship between hemodynamic stress and leptomeningeal arterial damage, especially in the watershed region.
