AbstractThe authors report the case of two sisters: each suffered from two intracranial hemorrhages caused by aneurysmal rupture at an interval of respectively 8 and 5 years. In the first case, the first subarachnoid hemorrhage (SAH) was related to a left middle cerebral artery aneurysm and the second, 8 years later, to the rupture of one of three right aneurysms (anterior communicating, supraclinoid internal carotid and middle cerebral arteries). But the "de novo" character of the right aneurysms could not be established. In the second case, the first SAH was related to an aneurysm of the right middle cerebral artery, with the left one appearing normal on the initial angiography. The second SAH, 5 years later, was related to a "de novo" left aneurysm. These two observations of familial, multiple and "de novo" intracranial aneurysms suggest a genetic basis for the pathogenesis of the arterial dysplasia. As in the literature, these hypothetical congenital factors could not be identified in both cases, but their probability justifies further investigations. If this factor exists, can we hope for a total recovery of the aneurysmal disease?
