A case of isolated bilateral pulmonary arterial calcification diagnosed in utero.

We report a very rare case of isolated multiple pulmonary arterial calcification with severe bilateral peripheral pulmonary arterial stenosis diagnosed in utero. Despite treatment with bisphosphonate for 6 months, systolic right ventricular pressure increased persistently and surpassed left ventricular pressure. After successful bilateral pulmonary arterioplasty at 13 months of age, the patient showed decreased systolic right ventricular pressure with normal interventricular septal configuration. This is the first case report for an isolated pulmonary artery calcification without other arterial calcification proven by non-contrast computed tomography of a living patient.
