Nonneoplastic vascular lesions of the middle ear.
Nonneoplastic vascular lesions in the middle ear may be arterial or venous. For the former, ectopic location of the internal carotid artery is the most common; a high jugular bulb is the most common venous abnormality. Both may be clinically misdiagnosed without radiographic studies and, in the event, lead to disaster.
