MRI-visible pericochlear lesions in osteogenesis imperfecta type I

Eur Radiol. 2000;10(10):1675-7. doi: 10.1007/s003300000429.


Osteogenesis imperfecta (OI) is an inherited generalized disorder of type-I collagen synthesis often associated with hearing loss. We present a case of OI type I in which hearing loss led to examination of the temporal bone with MRI. In the osseous otic capsule MRI demonstrated pericochlear lesions with soft tissue signal intensity and contrast enhancement. Changes similar to otosclerosis have been described in the temporal bone of OI patients when applying CT, but reports on MRI findings do not yet exist.
