[Necrotizing pneumonia in children - case report of a severe disease].

Necrotizing pneumonia is a rare but potentially life-threatening complication of community-acquired pneumonia in children. It is characterized by extensive pulmonary parenchymal destruction, necrosis, and formation of thin-walled cavities. We present the case of an 18-month-old child in whom, despite timely initiation of guideline-based antibiotic therapy, progressive disease and life-threatening bronchopleural complications developed, necessitating surgical intervention. This case highlights the importance of early recognition of therapy-resistant pneumonia, appropriate imaging diagnostics, and multidisciplinary management. Orv Hetil. 2026; 167(15): 605-608.
