A rare case of idiopathic central hypoventilation syndrome

Abstract

Central hypoventilation syndrome has been reported in children as a rare congenital disorder with associated Hirschsprung disease and several neural crest tumors. In adults, hypoventilation syndromes are usually associated with obesity, chest wall and neuromuscular disorders, and lower airways obstruction. We report a rare case of idiopathic central hypoventilation syndrome in an adult, nonobese man without any comorbidity who presented to us with chronic type 2 respiratory failure.
