Pulmonary Sequestration 
An axial CT scan (top) of a 31-year-old woman with an intralobar sequestration shows a left lower pneumonia (arrowhead) with a surrounding region of emphysema . A reformatted coronal image (bottom) shows a systemic artery arising from the descending aorta (arrow) that supplies the sequestration. Ashley Davidoff TheCommonvein.net -
