[Bilateral frontal infarct with imitation and utilization syndrome in a case of giant cell arteritis]. / Infarto frontal bilateral con síndrome de imitación y utilización en un caso de arteritis de células gigantes.

Giant cell arteritis (GCA) is a vasculitis which involves in a systemic fashion the mean and medium sized arteries. Intracranial vessels are exceptionally involved. Thus, stroke is an uncommon complication. We report a patient with typical GCA with blindness due to occlusion of the central artery of the retina, who developed an imitation and utilization behavior attributable to bilateral frontal infarction without accompanying neurological symptoms. Although histological study was not available, this case fulfilled all of Russi's criteria for GCA localized in the CNS. This lends support to the suspicion that the bilateral frontal infarction might be due to it.
