Case report

A 30-year-old woman (G3P2), with a non-contributive history and from a non-consanguineous marriage, presented to our department at 30 weeks of her pregnancy. Our ultrasound examination revealed polyhydramnios and multiple cystic areas within the lungs (the biggest one measured 29x15 mm), suggestive of a congenital cystic adenomatoid malformation of the lungs, type I. The heart was shifted to the left. No other anomalies were found. The patient was rescanned at 38 and 39 weeks and the findings were the same. A 3865 g female neonate was delivered at term and was moved to the neonatal intensive care unit due to the respiratory distress. Postnatal X-ray and CT were done confirming the diagnosis of the congenital cystic adenomatoid malformation of the lungs, type I.

Images 1, 2: 30 weeks; the images show a transverse (image 1) and a parasagittal (image 2) scans of the fetal thorax with the cystic lesions consisting with the congenital adenomatoid malformation of the lungs, type I.

Images 3, 4: 30 weeks; the images show a transverse (image 3) and a parasagittal (image 4) scans of the fetal thorax with the cystic lesions consisting with the congenital adenomatoid malformation of the lungs, type I. The heart is shifted to the left side (image 3).

Images 5, 6: 30 weeks; the images show a parasagittal color Doppler (image 5) and a transverse gray scale (image 6) scans of the fetal thorax with the cystic lesions consisting with the congenital adenomatoid malformation of the lungs, type I.
