We review the similarities and differences in these two conditions, and the antenatal ultrasound findings that allow correct prenatal identification and differential diagnosis. The common clinical presentation in infancy is respiratory distress and tachypnoea due to associated pulmonary hypoplasia, pulmonary overcirculation and/or pulmonary hypertension. Fig. The lung and airways have the important role of bringing fresh air from the environment to the alveoli, to enablea gradient for the oxygen and carbon dioxide to be exchanged, to facilitate the uptake of and removal of the gases from the blood stream and to transport the carbon dioxide to the environment. 820 Jorie Blvd., Suite 200 Oak Brook, IL 60523-2251 U.S. & Canada: 1-877-776-2636 Outside U.S. & Canada: 1-630-571-7873 Case 1.
