Abstract
Scimitar syndrome or veino-lobaire syndrome (term coined by Felson) is a very rare disease characterized by the combination of cardiopulmonary anomalies, in particular an anomalous right pulmonary venous return, located mostly in the inferior vena cava. We here report the original case of a 6-month-old female infant presenting with acute dyspnea. The diagnosis was suspected on the basis of thoracic radiograph and was confirmed by tomodensitometry which showed a large single right pulmonary vein draining into the right atrium associated with dextrocardia and pulmonary sequestration. The prognosis was based on the size of the left-right shunt and related malformations.
