A 14-year old boy with neurofibromatosis type I underwent surgery for severe kyphoscoliosis (Fig. 1A). Impaired ventilation led to the termination of the procedure. Investigation revealed tracheal compression by the innominate artery and a tumour (Fig. 1B–D). The latter was excised via right thoracotomy (Fig. 2). Histology revealed neurofibroma.

(A) Chest X-ray: severe kyphoscoliosis; (B–D): computed tomography scan: trachea compressed between the innominate artery and a tumour, identified after surgery as neurofibroma.
