title: Lesions simulating glomus tumors of the middle ear.
abstract: Several non-glomus middle ear masses may mimic glomus tumors. Clinical features alone may not be sufficient to differentiate these lesions. Radiography, particularly angiography is valuable in establishing the diagnosis in most cases. In some, however, diagnosis can only be made on tympanotomy. Four case reports are included in which the diagnosis turned out to be hemangioma, meningioma, high jugular bulb, and cholesterol granuloma. Careful assessment of the clinical, radiological, and operative findings is essential in order to avoid serious complications.
