目的研究肺部真菌感染的CT诊断以及与其他疾病的鉴别诊断。方法本院选择2010年8月~2012年8月间诊治的62例肺部真菌感染患者,对其进行CT检查。结果本文所选的患者中,10例以多发结节病灶,均为隐球菌感染,其中4例能够看到晕轮征;20例患者以肿块、单发结节以及空洞影为主,其中10例为曲霉菌感染,6例为毛霉菌感染,4例为隐球菌感染;14例患者主要表现为磨玻璃影,其中8例为念珠菌感染,4例为毛霉菌感染,2例为卡氏肺孢子菌病;18例主要表现为肺部实变影,其中8例为假丝酵母菌感染,10例为毛霉菌感染。结论肺部发生真菌感染CT检查得出除了霉菌球外,还有很多种,菌群复杂多变,没有特异性,诊断时不但要密切结合影像学检查,同时还要结合临床体征,如有必要可进行穿刺活检以及纤维支气管镜检查等。 Objective To study CT diagnosis of pulmonary fungal infection and its differential diagnosis with other diseases. Methods The hospital selected from August 2010 to August 2012 62 cases of pulmonary fungal infection diagnosis and treatment of their CT examination. Results Of the patients selected in this study, 10 cases had multiple nodules and were all cryptococcal infections, of which 4 cases were able to see the halo sign. Twenty patients had lumps, solitary nodules and empty voids, of which 10 Infections were caused by Aspergillus, 6 were Mucor, and 4 were Cryptococcal infections. Fourteen patients were ground with glass, of which 8 were Candida infections, 4 were Mucormycosis, and 2 were Carus Pneumococcal disease; 18 cases of the main manifestations of lung consolidation, of which 8 cases of Candida infection, 10 cases of Mucormycosis. Conclusion Pulmonary fungal infection CT examination showed that in addition to mycosphere, there are many kinds of flora complex and varied, there is no specificity, the diagnosis should not only be closely combined with imaging studies, but also combined with clinical signs, if necessary Can be biopsy and fiberoptic bronchoscopy.
