Abstract
Carotid pseudoaneurysms of petrous localization are rare. They are mostly due to trauma,
tumoral or infectious diseases, or a result of iatrogenic complications after skull
base surgery. Symptoms such as facial paralysis are exceptional and have rarely been
described in the literature until now. We report the case of a 64-year-old woman,
who developed left peripheral facial paralysis induced by two carotid pseudoaneurysms
in their intrapetrous section. The treatment is endovascular, despite the high morbidity
rate. She was first put on antiplatelet medications, before the left carotid aneurysm
was bypassed thanks to a self-expanding pipeline-type stent with flow diversion. The
left peripheral facial paralysis was due to the compression exerted by the left carotid
aneurysm, probably a congenital malformation. The progressive palsy recovery was fist
due to the aneurysmal thrombosis, then to the secondary fibrosis.
