Pulmonary hypertension in children is commonly caused by underlying cardiac and pulmonary disease. Within the past 10 years, scurvy has been identified as a cause for pulmonary hypertension. We describe the case of a 3-year-old autistic boy with undiagnosed scurvy who was scheduled for cardiac catheterization. Immediately after induction, the patient became hemodynamically unstable, which worsened with administration of nitrous oxide. Cardiac catheterization revealed pulmonary hypertension, which dramatically improved with administration of vitamin C. Anesthesiologists should be aware that scurvy is more common than previously thought, even in developed countries and can cause unexpected circulatory collapse from pulmonary hypertensive crisis.
