A female infant was born at term after an uneventful pregnancy by a cesarean section due to prolonged labor and cephalopelvic disproportion. Her birth weight was 3,266 grams, and the Apgar score was 7 at 1 minute and 9 at 5 minutes. After birth she presented with tachypnea and dyspnea. She was the transferred to the newborn intensive care unit. Axial (Figs 1A,
1B), coronal (Fig 1C), and reformatted (Fig 2) computed tomographic images showed multiple cystic lesions in both lungs. The patient had an eventful course and died of respiratory failure.
The photography from autopsy (Fig 3) showed multiple cystic dilatations in both lungs. The pathology showed flattened alveolar lining cells in these cysts with variable-sized cysts ranging from 3 cm to 7 cm in size. The findings were consistent with type 4 congenital cystic adenomatoid malformation.
