Unruptured anterior communicating artery aneurysms presenting with seizure: Report of three cases and review of literature
This 57-year-old right handed gentleman, hypertensive since 5 years, presented with one episode of generalized tonic clonic seizure early in morning while getting up from bed. He had no significant past medical history including any history of seizures. General, systemic, and neurological examination was unremarkable, and scalp EEG did not show any epileptiform discharges. MRI and CT brain [] showed a well defined hyper dense lesion of size 20 × 16 mm in the suprasellar region. DSA revealed a partially thrombosed, lobulated aneurysm, the flowing part having a size 7.19 × 6.66 mm arising from the anterior communicating artery, directed inferiorly, with a neck of 3.2 mm. Patient underwent thrombectomy and surgical clipping of the aneurysm. The brain surrounding the aneurysm appeared gliotic and was partially removed. The patient has remained seizure free on one year follow-up on antiepileptic medication.
