ABSTRACT
The authors report a giant cell arteritis case associating trismus and hemifacial oedema in a febrile context. After spontaneous regression of other manifestations, the apparition of more typical signs allowed to associate the diagnosis of temporal arteritis, later confirmed histologically. Thus, when facing a trismus case, even more when fever is present, it seems important to associate with the Horton's disease, no matter what the antecedents found at the interrogatory be, whether initial or isolated. The Doppler reveals flux abnormalities of the superficial branches of the external carotid. The examination of facial, temporal and internal maxillary arteries has a good negative predictive value in this pathology. It would be useful in therapeutic supervision.
