Aneurysms and epilepsy: an increasingly recognised cause

Intracranial aneurysms have rarely been reported in association with complex partial seizures. We report five cases of complex partial seizures where aneurysms were found either accidentally or through investigations in these patients. MRI scans and angiograms revealed these aneurysms and in one patient several aneurysms were found. Four patients were treated with GDC coil embolisation with follow-on anti-epileptic medication. Two of the patients have reported a few minor seizures despite the treatment. The seizures in the other two patients have resolved completely after the treatment. The fifth patient is on anti-epileptic medication. We review the possible pathogenesis for the link between aneurysms and seizures. The treatment of intracranial aneurysms is also reviewed.
