An 11-year-old boy presented with progressive proximal muscle weakness and areflexia. He also had scoliosis with right convexity in the thoracic spine. Nerve conduction studies showed demyelination with conduction blocks. The level of protein in the cerebrospinal fluid was elevated. Magnetic resonance imaging of the lumbosacral spine showed enhancement and hypertrophy of the nerve roots. The patient responded well to steroids. The association of acquired scoliosis with chronic inflammatory demyelinating polyneuropathy has not been reported before.
