Distal cortical middle cerebral artery (MCA) aneurysm is a rare entity. Despite the challenging procedure, the role of endovascular treatment is emerging due to its safety and efficacy in obliterating the microaneurysm. We report a 25-year-old male, who presented with a history of dizziness and headache for almost 2 weeks. Computed tomography scan showed a right front parietal subdural hematoma (SDH). We could not identify any underlying defining etiology of SDH neither head injury nor coagulopathy disorder. Therefore, diagnostic cerebral angiogram was performed, which showed a microaneurysm in the distal right MCA cortical branch. Hence, complete obliteration of this microaneurysm was performed using Onyx for endovascular embolization. Therefore, this case report demonstrates the efficacy of this modality in the treatment of microaneurysms with SDH.
