Angiogram-negative atraumatic subarachnoid hemorrhage (SAH) in a perimesencephalic
pattern on computed tomography (CT) is associated with an almost invariably favorable
prognosis with few rebleeds. We report a patient who exhibited a perimesencephalic
hemorrhage pattern on CT and negative serial angiograms and who presented with severe
neurologic disability from a concurrent midbrain stroke. We contend that both the
acute infarction and hemorrhage arose from obliteration of a penetrating end artery.
Possible etiologies of angiogram-negative SAH, including perimesencephalic hemorrhage,
are discussed.
