目的:探讨肺部真菌感染的CT表现。方法:回顾性分析20例经病理、真菌培养及随访证实肺部真菌感染患者的CT影像资料。结果:肺部炎性浸润实变17例,病灶分布多个肺叶或肺段,CT表现为斑片状或片状模糊影,密度不均,5例可见空气支气管征;肺部单发结节2例,呈类圆形,直径0.8～1.5 cm,多发结节16例,结节大小不等,边缘轮廓欠光整,肺部肿块6例,直径3～5 cm,形态不规则,密度欠均匀,9例结节及肿块内可见空洞形成,洞壁厚薄不一,外壁清晰,内壁较光滑,2例见“含气新月征”。结论:肺部真菌感染CT表现具有共同特点,CT有助于肺部真菌感染诊断。
Objective: To investigate the CT findings of pulmonary fungal infection. Methods: CT images of 20 patients with fungal lung infection confirmed by pathology, fungal culture and follow-up were retrospectively analyzed. Results: There were 17 cases of inflammatory infiltration in the lungs. There were multiple lobe or lung segments in the lesions. The patchy or patchy cysts appeared on the CT images with uneven density. Air bronchial signs were found in 5 cases. The solitary pulmonary nodules 2 cases were round, diameter 0.8 ~ 1.5 cm, multiple nodules in 16 cases, nodules of different sizes, the edge of the outline of poor light, 6 cases of lung mass, diameter 3 ~ 5 cm, irregular shape, density Uniform, 9 cases of nodules and the formation of hollow cavity can be seen, the wall thickness varies, the outer wall is clear, the inner wall is smooth, 2 cases see “gas crescent sign.” Conclusion: CT findings of pulmonary fungal infection have common features, CT can help the diagnosis of pulmonary fungal infection.
