Sixty four multiple intracranial aneurysm cases have been analysed for the purpose of identifying the relation between aneurysm rupture and aneurysmal features, mass signs, vasospasms and locations of the aneurysms. 1) 85% of the larger and largest aneurysm in each case were the ruptured aneurysm. 2) Aneurysms with a greater ratio of length to width showed a high frequency of rupturing. 3) Irregularities of the aneurysmal wall and the existence of a daughter aneurysm attached to the main aneurysm have a tendency to rupture. 4) Evidence of mass signs, associated with intracerebral, subarachnoid and subdural hematoma or a cerebral edema is also useful for the identification of the ruptured aneurysm. 5) Anterior communicating artery aneurysms have a relatively high frequency of being the ruptured aneurysm in cases of multiple aneurysm. 6) By utilizing all the investigated factors of the angiogram, the ruptured aneurysm might be identified in about 90% of the cases of multiple aneurysms.
