A Scutum Presenting as a White Mass Behind an Intact Tympanic Membrane

Abstract

The lateral wall of the middle ear is formed largely by the tympanic membrane and to a lesser extent by scutum. A white mass behind an intact tympanic membrane is usually associated with congenital cholesteatoma, middle ear tympanosclerosis, middle ear adenoma and an osteoma of the ossicular chain. The scutum eggshell appearance caused by hyperpneumatization should not be mistaken for other pathologic conditions.
