【摘要】：目的：探讨原发性肺部真菌感染的特征性CT表现,以提高诊断和鉴别诊断水平。方法：收集2004年到2012年的18例原发性肺真菌感染病例,复习其CT表现和临床资料,分析和总结原发性真菌感染的CT特征性表现。全部病例均经临床治疗性诊断、手术病理证实或血清学检查确诊。结果：18例原发性肺部真菌病患者CT均表现为软组织密度结节(15/18)或肿块(3/18)。经病理及血清学检查,12例为曲霉菌感染,3例为新型隐球菌感染,3例为球孢子菌。曲霉菌感染的CT表现：类圆形病灶(12/12)、分叶征及毛刺征(6/12)、支气管穿过征(3/12)、空气新月征(6/12)、两肺门及纵隔肿大淋巴结(3/12),6例CT增强扫描3例无强化,3例轻度强化。新型隐球菌感染的CT表现：均为菜花状病灶,可见分叶及毛刺征,内见钙化灶,两肺门及纵隔未见肿大淋巴结,CT增强扫描均表现部分强化。球孢子菌感染的CT表现：均为不规则病灶,周围可见晕征,两肺门及纵隔淋巴结肿大。结论：原发性肺部真菌病CT多表现为结节或肿块,增强扫描不强化或轻度强化,“空气新月征”是曲霉菌感染的特征,新型隐球菌病灶呈“菜花样”且伴钙化,“晕征”在球孢子菌病多见。
[Abstract]:Objective: to investigate the CT features of primary pulmonary fungal infection in order to improve the diagnostic and differential diagnosis. Methods: eighteen cases of primary pulmonary fungal infection from 2004 to 2012 were collected, their CT manifestations and clinical data were reviewed, and the CT features of primary fungal infection were analyzed and summarized. Results the CT findings of 18 cases of primary pulmonary mycosis were as follows: soft tissue density nodule 15 / 18) or mass 3 / 18. Pathological and serological examination showed that 12 cases were aspergillus infection and 3 cases were new cryptospheres. The CT findings of Aspergillus infection were as follows: round lesions 12 / 12, lobular and hairy signs 6 / 12, bronchial crossing sign 3 / 12, air crescent sign 6 / 12, enlarged lymph nodes of both hilum and mediastinum in 6 / 12, CT enhancement in 3 cases. The CT findings of Cryptococcus neoformans infection were all cauliflower lesions. Lobular and burr signs were seen, calcified foci were seen inside, CT enhancement was partially enhanced in both hilar and mediastinal lymph nodes. Ct manifestations of globosporidium infection were irregular lesions and halo signs around them. Enlargement of both hilar and mediastinal lymph nodes. Conclusion: the CT features of primary pulmonary mycosis are nodule or mass, no or slight enhancement on enhanced CT scan, and "air crescent sign" is the characteristic of aspergillus infection. The focus of Cryptococcus neoformans is "vegetable pattern" with calcification, and halo sign is more common in globocystis.
