Background: Cerebral angiography including internal and external carotid artery injections is crucial in young patients with a spontaneous subdural hematoma. Case Description: We present the first reported case of an accessory meningeal artery aneurysm in a 46-year-old male with a history of hypertension that led to a spontaneous nontraumatic acute subdural hematoma. A PubMed review of the literature was performed using a keyword search to identify cases examining nontraumatic spontaneous intracranial hematomas related to meningeal artery aneurysms. The literature review summarizes all published reports of middle meningeal artery aneurysms resulting in nontraumatic acute intracranial bleeds. The patient underwent successful coiling of the accessory meningeal artery. Conclusion: We propose endovascular treatment for accessory meningeal artery aneurysms and emphasize the utility of angiography of internal and external carotid arteries in a patient with an unexplained intracranial hematoma.
