大叶性肺炎的临床与CT表现

Clinical manifestation and CT features of lobar pneumonia

目的 探讨大叶性肺炎的临床与CT表现。方法 收集18例临床证实的大叶性肺炎,男15例,女3例,年龄17—84岁,平均58.1岁,均行血常规、胸部平片及CT检查。结果 本组10例临床表现不典型,其中1例为体检者。15例WBC均升高,除3例早期胸片外,胸片及CT显示单个或多个肺段或肺叶分布的均质实变或斑片状密度增高影,实变肺组织体积不缩小,内可见“含气支气管征”。结论 CT与本病的临床表现密切相关,CT应成为本病较早期诊断的依据之一;肺叶或肺段分布的均质性实变,受累肺组织体积不缩小,内见“含气支气管征”,或肺窗所示的斑片状密度增高影范围比纵隔窗所见明显示扩大是本病的典型CT征象。

Prupose To explore the clinical manifestations and CT features of from lobar pneumonia. Methods Blood routine examination, chest radiography and CT were accomplished on 18 patients suffering from lobar pneumonia proved by clinical signs and symptoms. Results Ten of 18 cases hadn't typical signs and symptoms of lobar pneumonia and one of 10 required routine physical examination. WBC fountincreased in 15 patients and even consolidation, mottling orpatchy shadow was in shown single or multiple lobars or segments in chest radiographes. The volume of the lung tissue with consolidation didnot reduce. Air bronchogram in CT image was found in 8 cases. Conclusion The fiandingss in CT image of lobar pneumonia is closely related to the clinical signs and symptoms, CT should be one of the early basic diagnostic means for this disease. Lobular and seg-mental consolidation, no volume reduction of effected lung, air bronchogram, and larger mottling zone with increased density in lung window than me-diastinal window are typical CT signs of the disease.
