Pulmonary hypertension without associated congenital heart defect is uncommon in children. When it occurs, pulmonary hypertension is usually caused by pulmonary arterial involvement and only rarely will primary pulmonary veno-occlusion be found. The symptom in pulmonary veno-occlusive disease is progressive "breathlessness," dyspnea on exertion.1-3
We studied a case of pulmonary veno-occlusive disease whose main symptom was severe, recurrent abdominal pain. As abdominal pain is a common childhood complaint, the associated increasing dyspnea was over-looked and the diagnosis of pulmonary veno-occlusive disease not immediately made.
