The imaging spectrum of bronchopulmonary sequestration.

Bronchopulmonary sequestration is a rare lesion characterized by abnormal lung tissue that lacks a normal bronchial communication and is supplied by an anomalous systemic artery. It has a variety of imaging appearances, including that of consolidation, a mass, or an air or fluid-filled cystic or multicystic lesion. This article reviews the imaging spectrum of bronchopulmonary sequestration, its important parenchymal mimics, and conditions that share the feature of anomalous systemic arterial supply to the lung.
