摘要
目的:分析肺部真菌感染的多层螺旋CT表现,提高诊断水平。方法:回顾性分析28例经病理、临床及实验室证实的肺部真菌感染的CT影像资料。结果:曲霉菌10例,白色念珠菌7例,隐球菌5例,放线菌1例,未明确分类的真菌5例。CT上表现为肿块或结节为主型9例;曲菌球型8例;空洞为主型6例;肺炎样实变或磨玻璃密度为主型5例。10例曲霉菌感染病例中有8例表现为曲菌球型,并可见"空气半月征"。结论:肺真菌感染CT影像表现复杂多样,但部分菌种感染有其常见的CT表现,当发现典型曲菌球伴"空气半月征"时可提示曲霉菌感染。
Objective： To evaluate the manifestation of pulmonary fungal infection on MSCT imaging, and to improve diagnostic accuracy. Methods： The CT findings of 28 patients with pulmonary fungal diseases confirmed by pathology, laboratory examination, and clinic data were analyzed retrospectively. Results： Of the 28 patients,10 patients were infected with aspergillus, 7 patients with Candida albicans, 5 patients with cryptococcus, 1patient with actinomyces, and 5 patients with unidentified pathogens. The CT features of pulmonary mycosis were：nodules or masses in 9 cases, aspergilloma in 8 cases, cavities in 6 cases, pulmonary consolidation or ground glass opacity in 5 cases. Eight of the 10 patients with pulmonary aspergillosis presented as aspergilloma with ＂air-crescent sign＂. Conclusion： The CT manifestation of pulmonary mycosis is heterogenous, but some CT images are common in patients with specific pulmonary fungal diseases. The typical aspergilloma with ＂air-crescent sign＂ can prompt the diagnosis of pulmonary aspergillosis.
