Bilateral Acute Subdural Hematoma from Ruptured Posterior Communicating Artery Aneurysm

Abstract

Brain tumors, hematological diseases and vascular malformations like fistulas or arteriovenous malformations are the most well known causes of non-traumatic subdural hematoma (SDH)1 Although spontaneous subdural hematoma from ruptured intracranial aneurysm has been reported2, SDH with non radiographic evidence of subarachnoid hemorrhage is very rare3,4. Moreover, a patient with acute and bilateral spontaneous subdural hematoma secondary to ruptured left posterior communicating artery aneurysm has not been reported to date. The clinical findings and etiologic mechanisms are discussed.
