Central neurogenic hyperventilation and renal tubular acidosis in children with pontine gliomas.

Central neurogenic hyperventilation (CNH) is a rare neurologic condition that develops secondary to brainstem involvement. Approximately 35 noncomatose patients with CNH have been reported, including 7 with either a diffuse (patients 2–10 in the table) or focal (patient 1 in the table) brainstem glioma.1–7 Although diffuse intrinsic pontine glioma (DIPG) is the most common pediatric brainstem cancer, only 1 case report described a child with DIPG who experienced CNH.6
