Thoracic spondylitis mimicking idiopathic scoliosis: a case report.

We report the case of a 12-year-old girl with thoracic spondylitis, who initially presented with a painless scoliotic deformity and was therefore misdiagnosed as having idiopathic scoliosis. Six weeks after initiation of brace therapy, increasing back pain necessitated admission. X-Ray, bone scintigraphy and magnetic resonance imaging then revealed a pathologic process in D8. To rule out a tumorous lesion, open biopsy was performed and led to the diagnosis of acute spondylitis. Treatment with oral antibiotics and bed rest led to a complete resolution of the scoliotic deformity, which clearly demonstrated that it was secondary to spondylitis. After 2 years, the girl is persistently well and free of pain. This unusual presentation of spondylitis delayed correct diagnosis and therefore specific treatment in the case of this 12-year-old girl.
