Abstract
- Aberrant internal carotid artery in the middle ear is a rare disease which, if unrecognized on radiological studies, can lead to serious complications during tissue biopsy. We report the imaging features of a case with aberrant internal carotid artery in the middle ear. A 60-year-old woman visited our hospital because of hearing difficulty on the right side. Temporal bone CT showed a well-defined mass of the right middle ear and lateral bony defect in the carotid canal adjacent to the mass. After arterial phase temporal bone CT with spiral CT andangiography, the mass could be diagnosed as aberrant internal carotid artery in the middle ear.
