Congenital pulmonary airway malformation (CPAM) is a rare congenital abnormality with unknown exact aetiology or clear genetic association. It is characterised by a failure of bronchial development and localised glandular overgrowth. Typically, it is diagnosed on prenatal ultrasound, only infrequently in children, and even less commonly in adults. We present a case of a 3-year-old boy, with no previous lung diseases who presented with fever for 1 week and fast breathing for 2 days suggestive of pulmonary infection. Chest xray suggestive of right sided consolidation and CT scan showed thin multiple cystic lesion with internal septations in basal segments of right with surrounding consolidation in superior segment of right lower lobe and posterior segment of right upper lobe suggestive of type 2 CPAM with secondary infective pneumonia. He was started on intravenous antibiotics. Blood culture suggestive of methicillin-resistant Staphylococcus aureus. He improved with antibiotic treatment. He was discharged with 6-week course of antibiotics and follow-up afterward.
