肺曲菌球的CT表现

CT presentation of pulmonary aspergilloma

目的分析肺曲菌球病的CT表现,提高对其认识。方法回顾性分析本院8例经病理或临床证实的肺曲菌球病的CT征象。结果 8例肺曲菌球患者中,青年患者(<30岁)2例,老年患者(≥60岁)6例。8例患者中慢性支气管炎伴肺气肿3例(其中合并支气管扩张2例),高血压、糖尿病2例,结核病2例,白血病骨髓移植术后1例。CT发现"空气新月征"4例,"气环征"3例,"球中含气征"1例。后2个征象同时出现者2例(其中合并"滚珠征"1例),6例增强CT检查的曲菌球增强后无强化。结论空气新月征、气环征、球中含气征、滚珠征及无强化是肺曲菌球病的相对特征性CT表现,了解这些征象有助于提高诊断水平。
