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.
