Cerebral aneurysm presenting with epilepsy.

Two patients with cerebral aneurysm are reported. Both presented with temporal lobe epileptic attacks. In one of the patients there was a family history of aneurysm and cerebral haemorrhage. One aneurysm was recognized by calcification on a plain radiograph but could not be demonstrated by angiography during life. The aneurysms were large and originated from the middle cerebral artery. Previous reports are reviewed. Difficulties of diagnosis and prognosis are discussed.
