肺曲菌病的CT表现及文献复习(附7例报告)

CT diagnosis of lung aspergillosis (7 cases report).

目的为了加深对肺曲球菌病的认识,提高CT诊断水平。方法总结分析经穿刺活检和支气管镜检确诊的肺曲菌病7例。结果CT表现主要为:空洞内可移动肿块及半月形空气征;蜂窝状改变中见小团块密影;软组织肿块,边缘可见“晕轮征”。结论肺曲菌病寄生于空洞内的病变诊断容易,侵袭性曲菌病,肺部形成肿块样浸润炎症,诊断较困难,需要病理或细菌学检查确诊。

Objective To enhance the recognition of CT signs of aspergillosis and improve the CT diagnosis.Materials Seven cases with lung aspergillosis confirmed by aspiration biopsy and bronchoscopy biopsy were Summarized and analyzed. Results The dominating manifestations were the followings: movable masses and semilunar air-sign in the cavities,dense shadow of small masses within the alveolate structure,soft tissue masses with halo-sign on the margin. Conclusion Aspergillosis which parasitizes inside a cavity is easily identified and diagnosed,whereas invasive aspergillosis and those resembling mass-like infiltrative inflammation are comparatively difficult to be diagnosed, so pathology and bacteriology examination are needed to help confirmation.
