Abstract
BackgroundCongenital pulmonary airway malformations (CPAM) are a spectrum of cystic and non-cystic anomalies arising from abnormal airway development in utero, with an incidence of 1 in 25,000 to 35,000 births. CPAM can present prenatally or postnatally with respiratory distress, recurrent infections, or occasionally as an incidental finding. This case series aims to highlight the clinical, radiological, and histopathological characteristics of CPAM through three pediatric cases, which include types 1, 2, and 3 CPAM. Case presentationCase 1: A four-month-old male presented with cough, cold, and respiratory distress. Imaging revealed hypoattenuation and overinflation of the left upper lobe with mediastinal shift. Left upper lobectomy confirmed CPAM type 2.Case 2: A one-month-old female presented with recurrent respiratory distress and infections. Imaging showed a large cystic lesion in the right middle lobe. Right middle lobectomy confirmed CPAM type 3.Case 3: A two-month-old male presented with dyspnea. Imaging showed a large bullae in the right chest with mediastinal shift. Right upper lobectomy confirmed CPAM type 1. Clinical discussionCPAM is a rare congenital lung malformation characterized by abnormal bronchial development and localized glandular overgrowth. Management involves surgical resection, with the timing of surgery dependent on symptomatology. Early identification and intervention are crucial for preventing complications such as pulmonary hypoplasia and recurrent infections. Histopathological examination post-resection is essential for accurate classification and management of CPAM. ConclusionThis case series provides valuable insights into the clinical, radiological, and histopathological features of CPAM, including the types encountered in each case. It underscores the importance of early diagnosis and timely surgical intervention, advocating for routine prenatal and postnatal screenings to effectively identify and manage CPAM.
