False aneurysm of the intracranial arteries occurs infrequently as a complication of head injury and rarely as a consequence of other pathology. A case of false aneurysm of the supraclinoid internal carotid artery following minor intraoperative injury during clipping of a basilar-superior cerebellar aneurysm by the pterional approach is described. False aneurysm is a potential cause of recurrent intracranial hemorrhage after successful aneurysm clipping. Arterial bleeding which appears to come from the region of a branch origin should be viewed with concern even if it subsides spontaneously.

Résumé:

Résumé:

Faux anévrisme iatrogénique après chirurgie pour anévrisme intracrânien. Un faux anévrisme des artères intracraniennes est une complication rare d’un traumatisme crânien ou suite à une autre pathologie. Nous décrivons un cas de faux anévrisme de la portion supraclinoïde de la carotide interne suite à un traumatisme mineur pendant une chirurgie pour clipper un anévrisme de l’artère basilaire cérébelleuse supérieure par voie ptérionale. Un faux anévrisme est une cause potentielle d’hémorragie intracrânienne récidivante suite au clippage d’un anévrisme. Un saignement artériel qui semble provenir de la région d’une bifurcation est un signal d’alarme, même s’il s’arrête spontanément.
