ABSTRACT
Objective: To describe the radiological characteristics of congenital pulmonary and airway malformations which are frequently found in pediatric patients, from three hospitals in Bogotá between the years 2010 - 2016. Materials and methods: Retrospective, observational and descriptive study with a sample of 27 patients, with an average age of 5 months, who met inclusion criteria: patients between 0 months and 17 years of age, with a confirmed diagnosis of congenital malformation of the lung, who underwent surgery for lung or airway lesion and whose histopathological study was compatible with congenital malformation of the lung. Results: The prevalence of congenital malformations is higher in females. 80% of cases had prenatal diagnosis, with cystic adenomatoid malformation being the most common and the main radiological feature being the cyst. Conclusion: Computed tomography allows detailed studies of these malformations, achieving greater accuracy compared to conventional techniques such as chest radiography and ultrasound.
