[X-ray findings in primary bilateral pulmonary hypoplasia-- correlation with pathologico-anatomical findings]

Comparative radiologic/pathologic study of 45 newborns with primary and secondary pulmonary hypoplasia. 43 cases were proven at autopsy. From 9 cases with primary pulmonary hypoplasia, 7 could be identified by 3 independent observers. The roentgen criteria of primary pulmonary hypoplasia are evaluated and should serve in the future to clinically diagnose this condition.
