Bruit caused by aberrant carotid artery in the middle ear.
An aberrant course taken by the internal carotid artery during its development may lead it through, rather than anterior to, the middle ear space. The resulting symptoms and signs, including a pulsatile bruit in and around the ear and the presence of a mass behind the tympanic membrane, require differentiation from those of glomus jugulare tumor.
