Approach to a symptomatic unruptured intracranial aneurysm presenting as status epilepticus: a case report and literature review.

Unruptured intracranial aneurysms are mostly diagnosed after hemorrhage from another aneurysm, or incidentally when evaluating neurological symptoms such as headache, ischemic cerebrovascular disease, and cranial nerve palsy. Seizure as a presenting feature is unusual. We reported a case of a 39-year-old woman who suffered status epilepticus caused by an unruptured intracranial aneurysm. Head magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), confirmed with cerebral angiography, revealed a large left internal carotid artery (ICA) saccular aneurysm. Mass effect resulting in direct compression causing seizures. Symptoms resolved after endovascular coiling was performed. We aim to present a case of seizure as a rarely considered manifestation of a symptomatic unruptured intracranial aneurysm. A treatment strategy prior to hemorrhage is essential.
