Pulmonary abscess is a rare but serious condition in pediatric patients, caused by severe pulmonary infection that leads to tissue destruction and necrosis. It can be classified as primary or secondary depending on the cause. Establishing an etiology in pediatric pulmonary abscesses is challenging, underscoring the essential role of advanced imaging techniques, such as computed tomography, in achieving an accurate diagnosis and differentiating among various conditions that may mimic lung abscess. While conservative management with antibiotics is the first line of treatment, some cases may progress and require surgical intervention. We present two clinical cases of pediatric lung abscesses, emphasizing the importance of timely intervention, accompanied by a brief review of current knowledge that highlights key clinical features, diagnostic challenges, and therapeutic approaches in pediatric lung abscess.
