Abstract
INTRODUCTION: This case demonstrates very late neurological deterioration due to a pseudarthrosis in the fusion mass after scoliosis surgery. Though not the first case in the literature, it is the first case in which pre-operative magnetic resonance imaging revealed that the compression was due to a cyst arising from the pseudarthrosis. CASE PRESENTATION: Twenty-two years after a successful correction and fusion for scoliosis, a 38-year-old Caucasian man presented with progressive numbness and significant weakness. As revealed by imaging, a cyst relating to an old pseudarthrosis was compressing the spinal cord. This was removed, and the cord decompressed, resulting in resolution of all symptoms. CONCLUSIONS: Lifetime care of patients with scoliosis is required for very late complications of surgery. Asymptomatic pseudarthroses have the potential to cause symptoms many years after surgery.
