Abstract:
A pulmonary varix is a localized dilatation of a pulmonary vein, which is usually asymptomatic presented as a mass on a chest roentgenogram, and diagnosed with pulmonary angiography. We encountered a case of 55 year-old man, in whom incidentally identified was a dilated blood vessel that passed through the minor fissure and returned to the inferior pulmonary vein, which we diagnosed as pulmonary varix. This vascular anomaly was accompanied by the occluded superior pulmonary vein, highly suggestive of the developmental mechanism of this disease.
