Congenital Lung Abnormality


Lung 3

Congenital lung abnormalities are being detected more frequently at routine high-resolution prenatal ultrasonography. The most commonly encountered anomalies include lung agenesis-hypoplasia compllex (pulmonary underdevelopment), congenital pulmonary airway malformation, congenital lobar overinflation, bronchial atresia, bronchogenic cyst, congenital high airway obstruction syndrome, scimitar syndrome and bronchopulmonary sequestration. Recognizing the antenatal and postnatal imaging features of these abnormalities is necessary for optimal prenatal counceling and appropriate perinatal and postnatal management.

With advances in both fetal ultrasonography and magneting resonance imaging, abnormalities of the thorax are increasingly being recognized antenatally, allowing providers to anticipate managementy issues at the time of delivery or later in neonatal life, and help parents comprehend the prognosis. Recognizing the imaging features of a variety of intra thoracic processes in the fetus is necessary for appropriate guidance of the clinicians caring for the mother.
