Primary Staphylococcal Lung Abscess: A Rare Situation in Infants

Abstract

Primary pulmonary abscess is a rare but serious localized bacterial infection of the lung parenchyma, occurring without prior lung conditions like bronchiectasis or necrotizing pneumonia. We report the case of an 11-month-old child with a 22-day history of productive cough and fever, unresponsive to initial antibiotics. Clinical examination showed a stable, eupneic child with mild fever and reduced oxygen saturation. Imaging revealed a large mass in the right upper lung lobe, necessitating surgical intervention. A thoracotomy confirmed a pulmonary abscess, and cytobacteriological analysis identified a resistant Staphylococcus spp. Postoperative recovery was successful following tailored antibiotic therapy. This case highlights the importance of comprehensive evaluation and timely surgical management in treating primary pulmonary abscesses in children.
