A case is presented of common pulmonary vein atresia (CPVA) in a fetus in utero, with severe pulmonary edema, bilateral pleural effusion, and a normal-sized heart, as diagnosed on ultrasound examination in the 35th week of gestation. The echodensity of the lungs was similar to that of the liver. The latter was enlarged and edematous, while the spleen was of normal size. These ultrasonic features are similar to findings in fetal cardiac failure. A midline enlarged blood vessel was identified posterior to the heart at the atrial level. It proved to be an atretic common pulmonary vein at autopsy examination.
