Pulmonary sequestration is a congenital malformation characterized by a pulmonary lobe or pulmonary segment that receives blood supply directly from the aorta. Classically, 2 forms are described. The first is intralobar sequestration, in which the anomalous lung tissue is contained within the visceral pleura. The blood supply comes directly from the aorta, and normal venous drainage through the pulmonary veins goes to the left atrium. The second form is extralobar sequestration, in which the abnormal lung tissue is separated from the normal lung by its own visceral pleural investment. The blood supply generally derives either from the abdominal aorta or the pulmonary artery, and the venous drainage is through the azygos vein or portal system.Go 1

The relevance of this pathologic condition derives from the difficulty in diagnosis and the risk of development of severe pulmonary and cardiovascular complications. Heart failure usually appears during the neonatal period or childhood and in most patients is associated with congenital cardiac defects.Go Go 2,3 We report the case of an adult patient without structural cardiac abnormalities in whom a dilated cardiomyopathy caused by an intralobar pulmonary sequestration undiagnosed for many years reverted after lobectomy.
