Description
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.
