Abstract

Spinal osteochondroms are very rare, and are thought to arise through a process of progressive endochondral ossification of aberrant cartilage of a growth plate, as a consequence of congenital defect or trauma. A case of diffuse type osteochondroma involving the posterior elements of L1-L5 that progressed after laminectomy in a 33-year-old man is reported. Usually, the spinal osteochondroma shows clear demarcation between tumor margin and normal spine elements, and can be exised completely. However, there was no clear demarcation between tumor and normal spine element in our case and therefore it was not possible to removal completely.
