Purpose or Case Report: Bronchopulmonary sequestration (BPS) is a rare congenital abnormality of the lower airway resulting in a mass of nonfunctional lung tissue. Our purpose is to present the prenatal and postnatal imaging findings of a spectrum of BPS cases and to correlate with pathology findings.

We present a series of BPS evaluated with prenatal imaging (US and MRI) and postnatal imaging (radiographs, US, CT, and MRI). Pathology will be reviewed.

Our series includes isolated BPS, hybrid BPS associated with cystic pulmonary airway malformation (CPAM), BPS associated with diaphragmatic hernia, and challenging cases of intradiaphragmatic, subdiaphragmatic, and mediastinal sequestrations that can mimic other masses. We also include a case of sequestration with an associated communication to the GI tract (bronchopulmonary foregut malformation) and a case of isolated BPS that spontaneously involutes over time.
