Congenital thoracic malformation.

To cite: Sharp C, Jackson J, Hands G. Thorax Published Online First: [please include Day Month Year] doi:10.1136/thoraxjnl-2013203708 A 31-year-old man presented with recurrent chest pain. CT coronary arteriography (figure 1) demonstrated a well-defined area of hypertransradiancy at the left lung base supplied by a large artery arising from the thoracic aorta (figure 2) with no normal bronchial or pulmonary artery communication, but normal pulmonary venous drainage. The diagnosis is that of congenital bronchial atresia with a systemic artery supply (also termed intralobar sequestration). Congenital pulmonary abnormalities are being detected increasingly frequently as incidental findings during cross-sectional imaging performed for other reasons. Management is usually conservative unless complicated by infection or haemoptysis.
