[Osteoid osteoma of the vertebral column as a cause of scoliosis].

After reminding how difficult it is to reach the diagnosis for an osteoid osteoma of rachis, the Authors report of a patient who was put under their observation after having been treated as lumbar scoliosis and discitis for one year. As they removed the osteoid osteoma, the painful symptomatology punctually disappeared and the rachis, after few months, was in its normal order.
