A 55-year-old man had hydrocephalus caused by a third-ventricular tumor. Mentation improved after ventricular shunting and radiation therapy. Progressive hyperphagia, obesity, memory impairment, and hypersomnolence developed 13 months later, and he died 2 years after diagnosis. At necropsy, a gangliocytoma filled the third ventricle, resulting in compression and necrosis of the ventromedial and posterior hypothalamic nuclei. Clinical manifestations were attributed to these lesions.

Idiopathic central hypoventilation has occasionally been reported in previously well children after infancy. The relationship between this late-onset central hypoventilation syndrome (LO-CHS) and congenital central hypoventilation syndrome (CCHS) has not been established. Both CCHS and LO-CHS have been associated with neural crest tumors, such as ganglioneuroblastoma and ganglioneuroma, and they generally occur in the presence of a histologically normal central nervous system. At least 10 case reports of idiopathic LO-CHS featured evidence of hypothalamic dysfunction (HD), including hyperphagia, hypersomnolence, thermal dysregulation, emotional lability, and endocrinopathies. We report on a case of LO-CHS/HD successfully treated by nasal intermittent positive pressure ventilation (NIPPV). Despite the commonalties with CCHS, we propose that LO-CHS/HD is a distinct clinical syndrome. In addition to the markedly different age at presentation, features of hypothalamic dysfunction are not seen in CCHS. Review of the literature was undertaken to further clarify the full spectrum of the disease.
