Abstract

A 46-year-old housewife suffered a fatal subarachnoid hemorrhage from an internal carotid aneurysm. Cerebral angiography performed during this hemorrhage demonstrated angiographic dye coursing up the internal carotid artery, entering the aneurysm, spouting into subarachnoid space, and flowing down the clivus. The roentgenographic demonstration of dye entering subarachnoid space was found in four fatal cases of bleeding aneurysm in the literature. The rarity of this phenomenon probably reflects the evanescence of the actual bleeding from a ruptured intracranial aneurysm.
