Osteochondroma is a benign tumour of the bone, predominantly involving long bones.In our case we report, a rare presentation of osteochondroma in the lumbar spine (L4) in an18 year old male patient.Osteochondromas are rarely seen in the spine and if found, are confined to the cervical-dorsal region.Very few cases have been reported till date of osteochondroma presenting in the lumbar spine.Even rare is an osteochondroma arising from the spinous process.In our case intra operatively a bony tumour with a cartilaginous cap was noted.Histopathology of the specimen confirmed the diagnosis of osteochondroma.Following excision of the tumour patient was symptom free.
