CT-guided extrapleural drainage of bronchogenic cyst.

A patient with a subcarinal bronchogenic cyst is described. The cyst was aspirated using an extrapleural percutaneous approach under CT guidance, employing repeated injections of 4-5 ml of saline to split the parietal pleura from the chest wall. Thus we describe a technique that allows the insertion of a catheter into a cyst and complete evacuation of its contents.
