Congenital cystic disease of the lung

A 15-year-old boy who had sharp pains in the right side of the chest and was unable to breathe deeply was tentatively diagnosed as having congenital cystic disease of the lung on the basis of chest x-ray studies and bronchography. The diagnosis was confirmed after thoracotomy and right lower lobectomy, carried out because of firm adherence of a large thick-walled cyst. The patient's respiratory function improved rapidly and chronic dyspnea resolved completely.
