Fig. 2. 1-day-old symptomatic female neonate with prenatal diagnosis
of Stocker type I congenital cystic adenomatoid malformation. Patient
presented with tachypnea and bradycardia after birth. Supine chest radiograph
shows opacification of left upper lobe with rightward deviation of trachea and
esophagus delineated by enteric tube. Fetal thoracentesis had been performed
in this patient to drain fluid from this giant unilocular malformation. Fluid
had reaccumulated resulting in mass effect and homogeneous opacity seen on
this radiograph.
