A case of mediastinal bronchogenic cyst assosiated with focal honeycomb lung

Abstract

We reported a 14-year-old female who was operated on a mediastinal bronchogenic cyst communicating with the right upper lobe and an abnormal bronchus. The patient had contracted pneumonia twice, and complained of a cold at this moment. Chest CT scan showed focal honeycomb part in S3 of the right upper lobe and a mediastinal cyst (3.0 × 3.0 cm) in the right side of the trachea. We diagnosed a mediastinal bronchogenic cyst communicating with focal heneycomb change in the right upper lobe under azygos arch through the abnormal bronchus. Combined resection of these leseions was performed. Histologically the cyst was diagnosed as bronchogenic and focal honeycomb lung of right S³ as severe inflammation of the lung, with no inflammatory change found in the cyst.
