[Pseudo-aneurysm of the internal carotid artery].

The authors recall the anatomy of the deep neck spaces and report the case of a 3-year-old girl with a parapharyngeal abscess followed by a pseudo-aneurism of the carotide artery. Ultrasonography, CT scan and angiography findings are described. This case puts in mind of the seriousness of neck abscesses. Each specific anatomical location must be definite for a better therapeutic approach on account of hemorrhagic risks of parapharyngeal abscesses.
