Congenital pulmonary airway malformation

Area of Science:

• Pediatric Pulmonology
• Thoracic Surgery
• Developmental Biology

Background:

• Congenital cystic adenomatoid malformations (CCAMs) are rare, sporadic lung developmental anomalies.
• Typically unilateral and single-lobe, CCAMs present as hamartomatous abnormalities with adenomatoid proliferation.

Observation:

• A 6-year-old girl presented with a 3-month history of prolonged fever and non-productive cough.
• Physical examination revealed coarse crackles and decreased breath sounds on the left side.
• Laboratory tests showed elevated markers for hydatid cyst (IgA and IgM).

Findings:

• Initial diagnosis suggested a hydatid cyst based on clinical presentation and serology.
• Intraoperative findings led to a revised diagnosis of adenomatoid cystic malformation.
• Surgical resection was performed with a favorable outcome.

Implications:

• This case underscores the importance of considering CCAMs in pediatric patients with persistent respiratory symptoms, even with initial atypical presentations.
• Accurate diagnosis is crucial for appropriate surgical management and patient outcomes.
• Highlights diagnostic challenges in differentiating CCAMs from other thoracic pathologies.
