✓ In a recent study from the Mayo Clinic on the natural history of intact saccular intracranial aneurysms, none of the aneurysms smaller than 10 mm in diameter ruptured. It was concluded that these aneurysms carry a negligible risk for future hemorrhage and that surgery for their repair could not be recommended. These findings and recommendations have been the subject of much controversy. The authors report three patients with previously documented asymptomatic intact saccular intracranial aneurysms smaller than 5 mm in diameter that subsequently ruptured. In Case 1, a 70-year-old man bled from a 4-mm middle cerebral artery aneurysm that had been discovered incidentally 2½ years previously during evaluation of cerebral ischemic symptoms. A 10-mm internal carotid artery aneurysm and a contralateral 4-mm middle cerebral artery aneurysm had not ruptured. Case 2 was that of a 66-year-old woman who bled from a 4-mm pericallosal aneurysm that had been present 9½ years previously when she suffered subarachnoid hemorrhage (SAH) from a 7 × 9-mm posterior inferior cerebellar artery aneurysm. Although the pericallosal aneurysm had not enlarged in the intervening years, a daughter aneurysm had developed. The third patient was a 45-year-old woman who bled from a 4- to 5-mm posterior inferior cerebellar artery aneurysm that had measured approximately 2 mm on an angiogram obtained 4 years previously; at that time she had suffered SAH due to rupture of a 5 × 12-mm posterior communicating artery aneurysm. These cases show that small asymptomatic intact saccular intracranial aneurysms are not innocuous and that careful consideration must be given to their surgical repair and long-term follow-up study.

Abstract BACKGROUND Seizures as the unique initial manifestation of unruptured intracranial aneurysms have rarely been documented and not systematically described until now. OBJECTIVE The purpose of this large retrospective analysis was to focus on the incidence of primary epileptogenic aneurysms and the influence of treatment on epilepsy. METHODS Within a 16-year period, 347 unruptured aneurysms were surgically treated at centers in Munich (1992–2002) and Düsseldorf (2003–2008), Germany. Of this patient population, 9 patients presented exclusively with epileptic seizures or epileptic equivalents. In 3 of them, a high-lying internal carotid artery aneurysm was diagnosed that was buried in the parahippocampal gyrus. In 4 patients, a middle cerebral artery aneurysm also created contact with the mediotemporal lobe adjacent to the parahippocampal gyrus. An anterior communicating artery aneurysm and a pericallosal artery aneurysm were diagnosed in 2 additional patients. Two patients with a middle cerebral artery aneurysm were initially incompletely occluded with Guglielmi detachable coils and continued to have epilepsy after the intervention. In all but 1 patient, the aneurysms were clipped and completely removed. RESULTS In all 8 patients operated on, there was no sign of hemorrhage intraoperatively but cortical gliosis was seen around the dome of the aneurysm. In all cases, the aneurysm and the surrounding gliosis, if existent, were surgically removed. Freedom from seizures without medication resulted for all patients after microsurgery. DISCUSSION Seizures as a presenting symptom of unruptured intracranial aneurysms are rare. There seems to be a preponderance of aneurysms anatomically related to the temporomedial region. Elimination of the aneurysm and perifocal gliosis provides the possibility of a cure for the epilepsy.

Cerebral Artery Aneurysm

AbstractSpontaneous intra-aneurysmal thrombosis occurs in approximately 50% of giant intracranial aneurysms. The incidence of this process is associated to location, size, and origin, and the natural history of spontaneous thrombosis occurrence in non-giant aneurysms is rare and still unclear. We describe two non-giant middle cerebral artery (MCA) aneurysms that spontaneously thrombosed and comment the aspects of the literature.
