Necrotizing pneumonia is a serious complication of pediatric pneumonia, characterized by liquefaction and cavitation of the lung parenchyma. Streptococcus pneumoniae and Staphylococcus aureus are the most implicated organisms. Mycoplasma pneumoniae has been an increasingly recognized pathogen, especially is Asian and Pseudomonas aeruginosa is mainly noted in a higher percentage of patients with complex chronic conditions. Clinical presentation typically includes fever, respiratory distress, and failure to respond to standard antibiotic therapy. These patients are more likely to have pleural involvement in the form of effusion or empyema and a higher need for respiratory support. Diagnosis is typically through a combination of chest radiographs, lung ultrasound, and chest computed tomography. Management is primarily via prolonged intravenous antibiotics that cover the above organisms, though pleural drainage with fibrinolytics is often required. Surgical intervention is often reserved for refractory cases that fail initial fibrinolytic therapy. Prognosis is usually favorable in the short and long term, though early recognition and appropriate management are imperative to reduce the duration of illness and morbidity.
