A rare cervical spine abnormality associated with neurofibromatosis.

Spinal abnormalities such as kyphoscoliosis and vertebral scalloping are frequent occurrences in type 1 neurofibromatosis (NF1). We report this rare case of posterior displacement of C3 vertebral body into the spinal canal causing severe cord compression associated with neurofibromatosis in a 13-year old girl. She underwent anterior excision of C3 vertebral body, bone graft and fixation of C2- C4, with improvement of her symptoms.
