title: Multiple cerebral de novo aneurysms.
abstract: The new development of two remarkable cerebral mirror aneurysms is described in two female patients, who had been surgically treated for a mid-line aneurysm several years previously. The phenomenon of mirror aneurysms makes it likely that an inborn weakness of the vessel wall is one of the underlying causes of cerebral aneurysms. Acquired alterations of the vessel wall and hemodynamic forces, on the other hand, also play an important role in the genesis of aneurysms.
