Agenesis of the lung--a rare congenital anomaly of the lung

Insights
Pulmonary agenesis, a rare lung defect, can occur without other major birth defects. Early investigation of chronic lung infections in infants is crucial for diagnosing this condition.
Area of Science:
- Pediatric Pulmonology
- Congenital Malformations
- Thoracic Surgery
Background:
- Pulmonary agenesis is a rare congenital anomaly characterized by the complete or partial absence of lung tissue.
- It is often associated with other significant cardiac and non-cardiac malformations, making diagnosis and management complex.
Observation:
- A case report of an eight-month-old infant girl presenting with chronic lung infection.
- The infant had right-sided pulmonary agenesis but no major associated cardiac or non-cardiac abnormalities.
Findings:
- This case highlights that pulmonary agenesis can occur in isolation, without other congenital defects.
- The severity of clinical presentation does not reliably exclude the presence of right-sided pulmonary agenesis.
Implications:
- Emphasizes the need for thorough investigation of congenital lung abnormalities, including pulmonary aplasia, in infants with persistent respiratory infections.
- Suggests that even mild or recurrent lung infections in infants warrant evaluation for underlying structural lung anomalies.
Abstract:
Pulmonary agenesis is a very rare condition and many of them are associated with a variety of cardiac and non-cardiac malformations. We report an eight-month old girl with chronic lung infection due to right sided pulmonary agenesis without any associated major cardiac or non-cardiac abnormalities. The case brings in forth the importance of investigating any infant presenting with features of chronic lung infection for any congenital abnormality of the lung including aplasia of the lung. This case also emphasizes that mildness of the attack does not exclude right sided aplasia of the lung.
