Middle meningeal artery aneurysm: Case report. 01-Aug-2017;8:172. Available from: http://surgicalneurologyint.com/surgicalint-articles/middle-meningeal-artery-aneurysm-case-report/
Background:Aneurysms of meningeal middle artery (MMA) are extremely rare. These aneurysms are of two types: true aneurysm and pseudoaneurysm. The true type is usually seen with pathologic conditions. Pseudoaneurysms, on the other hand, are associated with a skull fracture. Epilepsy caused by MMA aneurysm has never been described to our knowledge. We report a case of true aneurysm isolated from MMA revealed by epilepsy.
Case Description:A 57-year-old patient with a history of high blood pressure developed epilepsy which was treated by valproic acid. Initial scalp electroencephalography (EEG) showed seizure activity arising from the right temporal area. Epilepsy had become drug-resistant. Cerebral angiography revealed an aneurysm of the right middle meningeal artery without any other intraparenchymal anomaly. The interrogation did not reveal any history of family aneurysm. The patient underwent surgery with coagulation of the aneurysm and the MMA. The aneurysm was intradural in contact with the temporal cortex, and the surrounding brain tissues were preserved. The operative follow-up was favorable with amelioration of convulsions with a single antiepileptic. We planned to stop antiepileptic treatment according to electroencephalograms.
Conclusions:Aneurysms of the MMA are rare. Their mode of revelation by seizures is unusual. The factors of rupture are not known. When isolated, their physiopathology is identical to that of the aneurysms of the Willis polygon. Their management uses the same techniques as for other cerebral aneurysms.

Aneurysms of the meningeal middle artery (MMA) are extremely rare in comparison with the frequency of cerebral aneurysms. Aneurysms of the MMA are of two types: true aneurysm and pseudoaneurysm.[
A 57-year-old patient, nonsmoker and occasional drinker, with a history of high blood pressure who had suffered from seizures for 18 years concomitant to the discovery of high blood pressure. Initial scalp electroencephalography (EEG) showed seizure’s activity arising from the right temporal area. A noninjected cerebral computed tomography (CT) scan was then performed without abnormality. It was then treated as vascular epilepsy by vaproic acid. The drug resistance of this epilepsy motivated cerebral angiography. The neurological examination was normal. Cerebral angiography revealed an aneurysm of the right middle meningeal artery without any other intraparenchymal anomaly [
The aneurysm of the MMA is rare.[
Aneurysms of the middle meningeal artery are rare. Their mode of revelation by the seizures is unusual. The factors of rupture are not known. They are often posttraumatic or the consequence of perturbation of the cerebral circulation induced by other associated pathologies. When isolated, their physiopathology is identical to that of the aneurysms of the polygon of Willis. Their management uses the same techniques as for other cerebral aneurysms.
