摘要

The spontaneous disappearance of a ruptured intracranial aneurysm is unusual and its mechanism remains incompletely understood. However, several hypotheses are put forward and are mostly found in Virchow’s triad. We report the case of a man who suffered subarachnoid hemorrhage by rupture of a blister aneurysm of the P1 segment of the left posterior cerebral artery. A control arteriography performed one week after the rupture showed a disappearance of the aneurysm and a significant vasospasm of the carrier artery. Angiograms performed at 3 weeks and 3 months confirmed this disappearance of the aneurysm and a return to normal artery size. Clinically the patient was doing well. Therefore his aneurysm was spontaneously declared cured. Several studies are needed to clarify the natural history of spontaneously thrombosed aneurysms and elucidate their occurrence mechanism in order to improve the management of intracranial aneurysmal pathology.
