Ledison Ferreira Zanini, Alexandre Tonelli Faria, Robertson Correia Bernardo, Renata Furletti Diniz, Emília Guerra Pinto Coelho Motta, Wanderval Moreira



ABSTRACT

Aberrant internal carotid artery is an anomaly of the embryogenesis of the vertical portion of the internal carotid artery, characterized by projection of the internal carotid artery into the middle ear, adjacent to the cochlear promontory. The authors report a case of a patient in which contrast-enhanced computed tomography and magnetic resonance angiography examinations were decisive to adequately characterize the anomaly, thus avoiding instrumental or surgical intervention, which could bear fatal consequences.

RESUMO

A artéria carótida interna aberrante é uma anomalia na embriogênese da porção vertical da artéria carótida interna, caracterizada pela projeção desta artéria no ouvido médio, adjacente ao promontório coclear. Os autores relatam um caso no qual a tomografia computadorizada contrastada e a angiorressonância foram decisivas, caracterizando adequadamente a anomalia e evitando intervenção instrumental ou cirúrgica, que poderia ter conseqüências fatais.
