肺毛霉菌病CT表现

CT Findings of Pulmonary Mucormycosis

目的探讨肺部毛霉菌病CT表现特征。方法搜集经手术、穿刺活检或痰培养证实的9例肺部毛霉菌患者的CT平扫和增强扫描资料,回顾性分析病变的形态、分布、密度。结果(1)9例中"反晕征"表现3例(33.3%),"分隔征"表现5例(55.6%),"楔形实变坏死征"表现6例(66.7%),"晕征"表现4例(44.4%),"空气新月征"表现1例(11.1%),合并2种或2种以上征象6例(66.7%)。(2)9例中,有糖尿病史4例,急性淋巴细胞白血病、肺结核、慢性肾功能不全、不明原因多年肺部空洞病史、慢性肺部感染各1例。结论免疫功能不全患者,肺部CT出现"反晕征"、"分隔征"或"楔形实变坏死征"时,应注意毛霉菌病可能。

Objective To investigate the CT features of pulmonary mucormycosis.Methods 9 cases of pulmonary mucormycosis confirmed by operation,puncture biopsy or sputum culture were retrospectively analyzed by plain and enhanced CT scans.Results(1)Of the 9 cases,3(33%)showed"reverse-halo sign",5(55%)showed"segregation sign",6(67%)showed"wedge consolidation necrosis sign",4(44%)showed"halo sign",1(11%)showed"air crescent sign",and 6(67%)combined with two or more signs.(2)Of the 9 cases,there were 4 cases of diabetes mellitus,1 case of acute lymphoblastic leukemia,1 case of tuberculosis,1 case of chronic renal insufficiency,1 case of pulmonary cavity disease with unknown causes for many years,and 1 case of chronic pulmonary infection.Conclusion In patients with immune dysfunction,when pulmonary CT shows"reverse-halo sign","separation sign"or"wedge consolidation necrosis sign",attention should be paid to the possibility of mucormycosis.
