[Pediatric lung abscess].

Pediatric pulmonary abscess, a rare complication of pulmonary infection or congenital malformation, is characterized by parenchymal necrosis and purulent cavitation. Diagnosis is established through thoracic imaging and microbiological investigations, whereas treatment is mainly based on prolonged antimicrobial therapy, with percutaneous drainage or surgical intervention considered in cases of therapeutic failure. Prognosis is generally favorable but requires follow-up to detect possible sequelae or an underlying pulmonary malformation.
