Pulmonary sequestration is a relatively rare condition in which a part of lung tissue has no or only a secondary connection with the tracheobronchial tree. Blood supply comes from the aorta in anomalous branches. Sequestrations may be intra- or extralobar. Gerle et al. include both types in the general term congenital bronchopulmonary foregut malformation. Two surgically confirmed observations of bilateral intralobar pulmonary sequestrations are reported. The clinical features are recurrent respiratory infections with cough, fever and purulent sputum. X-rays only show nonspecific alterations. Chronic changes in the lower lobes should draw attention to pulmonary sequestration. Thoracic aortography is the procedure of choice in establishing the diagnosis and should always be carried out preoperatively. Segmental resection or lobectomy is the indicated treatment.
