Thoracic coarctation associated with neurofibromatosis.

A child with neurofibromatosis and hypertension also demonstrated renal artery stenosis, the most common cause of hypertension in children with neurofibromatosis; abdominal coarctation, which has previously been described; and thoracic coarctation, which to our knowledge, has not been previously reported. Rib notching may appear in patients with uncomplicated nueorfibromatosis, but the possibility of associated thoracic coarctation must also be considered in these patients.
