Computed tomography scan showing bronchopulmonary sequestration

Four images from a contrast-enhanced CT study of a 2-month-old infant with BPS. The top 2 images demonstrate abnormal lung tissue (arrows), consistent with BPS, in the posterior right lower lobe. The lower 2 images demonstrate an extremely large feeding artery arising from the thoracic aorta just above the diaphragm (arrowhead).
