Giant Unruptured Middle Cerebral Artery Aneurysm Presenting with Complex Partial Seizure: A Short Review.

Intracranial aneurysm is a rare cause of seizure although few cases may develop new onset seizure following rupture of aneurysm. The causes of seizure in ruptured aneurysm may be caused due to presence of subarachnoid hemorrhage, intracerebral hematoma, infarct due to progressive vasospasm, worsening of hydrocephalus, or even after surgical craniotomy for clipping of aneurysm. However, incidental aneurysm solely presenting with complex partial seizure is not reported in literature. To the best of knowledge of authors, current case represents the first case as incidental aneurysm presenting with seizure and pertinent literature is briefly reviewed.
