title: Cyanosis revealing hepatopulmonary syndrome in a child with dyskeratosis congenita.
abstract: We report the case of a 5-year-old child with dyskeratosis congenita who presented cyanosis and dyspnea at exertion. He had severe hypoxemia with elevated alveolar-arterial oxygen gradient in the setting of liver disease. Technetium-99m-labeled macroaggregated albumin scan showed abnormally high uptake in the brain, confirming hepatopulmonary syndrome.
