Abstract
Pulmonary sequestration is a congenital malformation in which a mass of pulmonary tissue is detached from the normal lung and receives its blood supply from a systemic arterys from the thoracic aorta or the abdominal aorta, or occasionally from an intercostal artery. We have experienced the three cases of the intralobar pulmonary sequestration. In the first case a 5 year old male was admitted of productive cough and abdominal distension, and chest film showed pneumonic infiltration in RLL. Second case was 26 year old male patient complaining Rt. chest discomfort and hemoptysis and chest X-ray revealed infiltration in Rt. LLF. Third case was 26 year old male patient whose complaint was hemoptysis. Chest x-ray showed hazy density in Lt. lower lung field. In the all cases, the aortograms were performed and the confirmed diagnosis was intralobar pulmonary seqeustration.
