Abstract
The authors present a case of congenital dysplasia affecting the long bones, skull, and other systems in a 7-year-old girl, with special attention to CT of the temporal bone, which showed abnormal ossicle fixation, a narrowed Eustachian canal, thickened sclerotic bone, and a small mastoid antrum and middle ear cavity. CT of the temporal bone can help one distinguish the etiologies of hearing loss associated with this disorder.
