Background: Bronchopulmonary sequestration is a rare congenital lung malformation, charactarized by an abnormal segment of bronchopulmonary tisue, irrigated by an anomalous systemic artery. Objective: To report the clinical course of an infant with an intralobar bronchopulmonary sequestration and review the most relevant aspects of this lung malformation. Case-report: A six months-old infant, treated for a pneumonia involving the right lower lobe, with persistence of the consolidation image for more than six weeks. Because of a computed tomography (CT) that showed an image suggesting a bronchopulmonay sequestration, the infant was scheduled for surgery, confirming the presence of the intralobar type of the malformation, which was removed without incidents. Conclusion: Bronchopulmonary sequestration is a rare congenital lung malformation, but it has to be considered in the presence of recurrent pneumonia or persisting consolidation images
