目的探讨炎症渗出型(Ⅰ型)塑型性支气管炎(PB)的CT表现及诊断和鉴别诊断。方法回顾性分析2例儿童PB患者的临床、影像及病理学资料。结合文献重点讨论其CT表现的特点。结果 2例炎症渗出型塑型性支气管炎共同的CT表现为:(1)支气管阻塞;(2)低密度肺实变;(3)无充气支气管征。结论当临床工作中遇到肺炎表现的患儿有无充气支气管征的密度偏低的肺实变时,且无异物吸入史,应考虑到炎症渗出型塑型性支气管炎的可能。
Objective To investigate the CT manifestations, diagnosis and differential diagnosis of inflammatory exudative (type Ⅰ) plastic bronchitis (PB). Methods The clinical, imaging and pathological data of 2 children with PB were retrospectively analyzed. Combined with the literature focus on the characteristics of CT performance. Results The common CT manifestations of inflammatory exudative bronchiolitis were as follows: (1) bronchial obstruction; (2) low-density pulmonary solidification; (3) bronchial insufflation. Conclusion When the clinical manifestations of pneumonia in children with or without low density of bronchial degeneration of lung consolidation, and no history of foreign body inhalation, should consider the possibility of inflammatory exudative bronchiolitis.
