Abstract/OtherAbstract:
BACKGROUND: Cavernous angiomas are responsible for intracranial hemorrhages, but bleeding is infrequently confined to the subarachnoid space.
METHODS: We describe an elderly, yet healthy man who sought medical attention for subarachnoid hemorrhage.
RESULTS: Vascular imaging failed to reveal a cerebral aneurysm, however magnetic resonance imaging done late in the course showed a cavernous angioma, on the surface of the left upper cerebellar peduncle, that had bled.
CONCLUSIONS: The so-called "angiography-negative" subarachnoid hemorrhage could have its source in small cavernous angiomas lying on the surface of basal skull brain structures.
