Case report 864. Elliptical, multicentric periosteal osteoid osteoma.
Overview
abstract
An extremely rare case of multicentric periosteal osteoid osteoma in a child was presented. The lesions were found to be embedded in a narrow elliptical strip, suggesting the possibility that lesional tissue was stretched in a longitudinal fashion as a result of the rapid skeletal growth. In young patients with stretched periosteal reaction who complain of pain, multicentric osteoid osteoma should be suspected. These nidi can be obscured by the exuberant periosteal reaction. Accurate evaluation of the radiographic findings is very important.
