Unruptured intracranial aneurysm presenting with epiletic seizure

Abstract

-Intracranial aneurysms are frequently present with subarachnoid hemorrhage.Less often they produce suggestive symptoms of cranial nerve dysfunction or intracranial tumor when very large. Their association with epilepsy has rarely been reported; such concurrence may not be a coincidence. When the patient presents with epileptiforme attacks the presence of an intracranial aneurysm is rarely considered. In this paper we report the case of a 45-years-old patient with an unruptured aneurysm of the middle cerebral artery with a 10 years history of epileptic seizure.KEY WORDS: intracranial aneurysm, epilepsy, middle cerebral artery, giant aneurysm. Epilepsia secundária a aneurisma cerebral não rotoRESUMO -Aneurismas intracranianos freqüentemente se apresentam com hemorragia subaracnóidea quando rotos, porém quando gigantes sangram com menor freqüência e se comportam como verdadeiros tumores, comprimindo estruturas cerebrais adjacentes, apresentando sintomatologia peculiar. Relatamos o caso de um paciente de 45 anos que apresentava crises convulsivas generalizadas com evolução de 10 anos. A investigação radiológica revelou presença de aneurisma gigante da artéria cerebral média, não roto. É realizada revisão da literatura correlacionando a presença de aneurismas não rotos e epilepsia, pois esta associação é pouco freqüente na literatura. PALAVRAS-CHAVE: aneurisma intracraniano, epilepsia, artéria cerebral média, aneurisma gigante.

Frontal lobe neuropathology presenting to Mental Health Services

“…Unruptured intracranial aneurysms are usually not associated with seizures. However, there have been reports of seizures associated with right middle cerebral artery aneurysms as in Mrs C [11]. It is doubtful whether the intracranial aneurysm in Mrs C was directly related to her clinical presentation.…”
