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.
