'Pulmonary sequestration is a congenital malformation characterized with the presence of a lung tissue not functioning normally and separated from the normal lung. It is nourished by systemic circulation and the venous drainage may be via the pulmonary system, azygos vein or portal system. There are two forms described; intralobar pulmonary sequestration and extralobar pulmonary sequestration. Bronchiectasis may develop around the sequestrated tissue due to relapsing infections. We aimed to present 4 adult patients in whom we performed surgery because of pulmonary sequestration.'
