Massive haemothorax caused by intralobar pulmonary sequestration

: The authors present the case of a young male with massive haemothorax caused by intralobar bronchopulmonary sequestration. Angiography is necessary for the exact diagnosis of bronchopulmonary sequestration. The most common site of intrapulmonary type sequestration is the left lower lobe of the lung. In this case the aberrant artery was originated from the abdominal aorta. During thoracotomy after ligature of the aberrant vessels S5,S10 segmentectomy was performed. The authors emphasize that the rare cause of rapid anaemia in consequence of haemothorax could be intralobar bronchopulmonary sequestration.
