[An unusual cause of secondary scoliosis: vertebral osteoblastoma].

We report the observation of a 22-year-old man suffering from nocturnal back pain for 2 years. The clinical examination shows a scoliosis. Imaging suggests either malignant tumor or an aggressive osteoblastoma of the sixth thoracic vertebra. After radical removal of the tumor, histopathologic examination confirms the diagnosis of osteoblastoma. Like any other neoplasma, osteoblastoma should be detected and removed early, before being responsible for non-reversing neurological complications.
