Monostotic Fibrous Dysplasia of the Lumbar Spine: Case Report and Review of the Literature

Abstract

Fibrous dysplasia has been frequently reported to involve the spine in the polyostotic form, but only rarely has monostotic fibrous dysplasia been noted. In the only previously reported case involving the lumbar spine, the disease was confined to the transverse process. The present case demonstrates monostotic fibrous dysplasia involving the vertebral body in addition to the posterior elements. The plain radiographic, computerized tomography, and histologic examinations are presented.
