Pulmonary Malformations Beyond the Neonatal Period

  • Chapter
Pediatric Chest Imaging

Part of the book series: Medical Radiology ((Med Radiol Diagn Imaging))

Abstract

Congenital lung malformations include a heterogeneous group of anomalies affecting the lung parenchyma, the arterial supply to the lung and its venous drainage (Heitzman 1984). From the morphological-radiological viewpoint, these malformations can be divided into two groups: focal malformations (congenital lobar overinflation, single congenital thoracic cyst, congenital adenomatoid malformation, pulmonary sequestration and isolated systemic supply to normal lung) and dysmorphic lung (lung agenesis-hypoplasia complex and lobar agenesis-aplasia complex).
