Late onset hypoventilation syndrome: is there a spectrum of idiopathic hypoventilation syndromes?

We report a case of late onset central hypoventilation syndrome (LO-CHS) with hypothalamic dysfunction (HD) and ganglioneuroma presenting at the age of ten years. LOCHS-HD is now a well-established syndrome; the key is to investigate each child's history and presentation to expeditiously offer the most accurate diagnosis and optimal management.
