Bronchogenic cyst causing pulmonary arterial occlusion

Abstract

A 33-year old woman had cough, chest pain, and fever. Chest CT scanning showed a cystic mass located just beneath the bifurcation of the trachea and caused pulmonary arterial occlusion. Lung perfusion scintigraphy showed no perfusion of the right lung. The cystic mass was excised completely and found histopathologically to be a bronchogenic cyst. Immediately after the cyst was excised, the right lung was not reperfused. However, 6 hours after the operation reperfusion lung injury occurred. Three months after the operation, lung perfusion scintigraphy showed reestablishment of perfusion of the right lung.
