目的探讨肺曲菌球的影像检查技术及X线表现。方法15例经手术病理证实的肺曲菌病患者,采用常规X线照片、体层及CT等检查技术,通过集体读片分析其影像学特征。结果与病理对照,单纯胸片检查诊断符合率60%(9/15),胸片加体层诊断符合率80%(12/15),而胸片加CT诊断符合率达93.3%(14/15)。其中较有特征的征象“新月征”40%(6/15),“气环征”20%(3/15),曲菌球可随体位改变33.3%(5/15)。结论“新月征”、“气环征”以及球形病灶随体位改变可作为肺曲菌球的影像学特征。
Objective To investigate the imaging technique and X-ray findings of pulmonary aspergilloma. Methods Fifteen patients with pulmonary aspergillosis confirmed by surgery and pathology were examined by radiography, tomography and CT, and their imaging features were analyzed by collective reading. The coincidence rate of the results with the pathological examination, simple chest radiography was 60% (9/15), the coincidence rate was 80% (12/15) in diagnosis of chest radiography, while the coincidence rate of chest radiography and CT was 93.3% (14 / 15). Among the more characteristic signs, 40% (6/15) of the “new moon sign” and 20% (3/15) of the “gas ring sign”, aspergillosis can change 33.3% (5/15) with the body position. Conclusion The “Crescent Moon sign”, “Gas ring sign” and spherical lesions with the change of position can be used as imaging features of pulmonary aspergilloma.
