　　儿童坏死性肺炎是社区获得性肺炎的严重并发症之一，目前定义尚不统一，其主要特点是肺实质损伤、坏死伴有空洞形成。虽然肺炎链球菌感染是儿童坏死性肺炎主要的发病因素，但是大部分仍未找到明确致病菌。儿童坏死性肺炎临床病情较普通肺炎重，并发症常见；及时行胸部CT检查有助于早期发现、早期诊断；治疗上仍以保守抗生素治疗为主，绝大部分病例预后相对较好。

Necrotizing pneumonia is a severe complication of community-acquired pneumonia in children, with no clear deif-nition currently, characterized by parenchymal injury, necrosis and cavity formation. Streptococcus pneumonia is the most common pathogen;however a positive microbiology is not always obtainable. The clinical manifestation of necrotizing pneumonia is more seri-ous than ordinary pneumonia, and complications are common. Chest CT scan is helpful to early detection and diagnosis. Antibio-tics remain the mainstay of treatment, and the prognosis is relatively well.
