Solitary Osteochondroma of L2 Spinous Process

Osteochondroma is the most common primary benign bone tumour frequently affecting the appendicular skeleton and rarely involves the spine and even more rarely involves the lower lumbar region. The present case report was a rare case of osteochondroma arising from spinous process of L2 vertebra. A 12-year-old male was visited with his parents with complaints of progressive painless swelling in the lower back for six months. After thorough evaluation osteochondroma arising from L2 spinous process was diagnosed. Patient was operated with extraperiosteal enbloc excision of the tumour along with L2 spinous process. Enbloc excision of axial exostosis should be considered owing to the risk factor of neurological involvement and rare malignant transformation.
