Both macroscopically and in the X-ray this tumor appearance very similar to osteosarcoma, especially the sclerosing type (Figs. 277, 278) (p. 206, this volume). An osteofibroma is usually seen as a single mass involving one bone (most often a vertebra). The bone is replaced by a radiographically dense, hard, bony mass which grows beyond the cortex of the bone and displaces but does not invade adjacent tissue. The preferred site is in a vertebra but long bones can be affected. Compression of the spinal cord by the tumor can occur with resulting posterior paralysis.
