肺曲菌病的CT诊断

目的探讨肺曲菌病的CT表现和诊断价值。方法本组病例6例,分别经手术病理和治疗随访证实。年龄32~60岁。5例有轻重不一的发热、咳嗽、胸痛、铁锈色痰或血丝痰,1例无任何症状和体征。采用SIEMENS SENSATION16层螺旋CT,6例均行CT平扫。肺窗:WW1 500Hu,WC-500Hu;纵隔窗:WW400Hu,WC40Hu。4例加行多方位图像重建(MPR)。结果6例中,病灶位于右肺2例,左肺4例。其中,2例表现为孤立性实质性结节,直径10~37 mm,类圆形,边缘可见棘突及"晕影";4例为空洞性结节,直径15~87 mm。空洞性结节中,2例具有"新月"征,2例具有"滚珠"征。结论肺曲菌病早期影像表现缺乏特征性,当病变局限形成曲菌球,尤其具备"新月征"和"滚珠征"者,是CT诊断的可靠依据。

CT Diagnosis of Pulmonary Aspergillosis

Objective To evaluate the CT appearance and diagnosis of the aspergillosis. Methods 6 patients with aspergillosis confirmed by operative pathology or therapeutic following- up were retrospectively analyzed . The patients with age from 32to 60 years old.Results The seven lesions with the longest dimention from 10 - 37 mm were respectively located at the right lung （2 cases） and left lung （4 cases）.The appearances of the pulmonary aspergillosis were followed as a solitary pulmonary nodule with the ＂hole sign＂ （2 cases） and a hollow lesion with the ＂meniscus sign＂ or ＂rolling ball sign＂ （2 cases） . Conclusion There might be no diagnostic specificity of the imaging appearances in early phase of the aspergillosis. The aspergilloma should be the special CT signs while with the ＂meniscus sign＂ or ＂rolling ball sign＂.
