RT Journal Article SR Electronic T1 Unusual presentation of a large tension bronchogenic cyst in an adult. JF Thorax JO Thorax FD BMJ Publishing Group Ltd and British Thoracic Society SP 951 OP 952 DO 10.1136/thx.48.9.951 VO 48 IS 9 A1 Tarpy, S P A1 Kornfeld, H A1 Moroz, K A1 Lazar, H L YR 1993 UL http://thorax.bmj.com/content/48/9/951.abstract AB A routine chest radiograph in a 20 year old man revealed a giant air filled cavity of the left hemithorax under tension. At thoracotomy a large left lower lobe intraparenchymal cyst required lobectomy and the pathological findings were consistent with a bronchogenic cyst. Although tension bronchogenic cysts are common in infants, this case demonstrates their unusual presentation in an adult.
