title: Solitary osteochondroma of the pedicle of L4 causing root compression. Case report.
abstract: Osteochondroma is about 50% of benign bone neoplasms and up to 15% of all primary tumours of the skeleton; metaphysis of long bones are more frequently involved with the spine being interested in 2.5-5% of all cases, usually pertaining to multiple osteochondromatosis, in which many areas of the skeleton are affected. A solitary osteochondroma of the right pedicle of L4 causing sciatalgic pain and difficulty warling and treated by surgery is presented. Only two other cases of solitary osteochondroma involving the lumbar spine have been previously reported.
