Pseudosubarachnoid Hemorrhage: A Zebra Worth Looking for

Authors: Joshua M. Ammerman, MD

Abstract

Nearly 30,000 individuals suffer spontaneous subarachnoid hemorrhage (SAH) annually in the United States, the vast majority due to a ruptured cerebral aneurysm. A smaller percentage of patients will suffer SAH of other etiologies, such as arteriovenous malformations, dural arteriovenous fistulae, spinal arteriovenous malformations, cerebral vasculitis, and hemorrhagic neoplasms.
