目的:探讨艾滋病合并肺部真菌感染的CT表现特点.方法:回顾性分析14例艾滋病合并真菌感染患者的胸部CT扫描资料.结果:病变主要位于肺外周、胸膜下或沿支气管分布,双肺散在或弥漫分布6例,局限性病灶8例,其中病灶位于肺下叶和/或中叶(舌叶)7例,右上叶4例,左上叶(除舌叶)1例.病灶呈大小不等结节影6例,单发类圆形肿块影2例,以空洞为主的病灶4例,小片状或大片状融合实变影5例,网结状影2例;纵隔及肺门淋巴结肿大3例,少量胸腔积液1例,高分辨力CT扫描显示树芽征3例.结论:艾滋病合并肺部真菌感染CT表现各异,主要表现为肺叶外周单发或散在分布大小不等结节伴或不伴空洞影、小片状或大片状实变影、网结状影及"树芽征",艾滋病患者CT扫描一旦出现此类征象,应高度警惕伴有真菌感染的可能.%Objective:To investigate the manifestations and value of CT in the dignosis of AIDS complicated with lung fungus infection. Methods:CT materials of 14 cases with AIDS complicated with fungus infection were retrospectively ana lyzed. Results;The lesions mostly located in lung periphery,approaching pleura or peripheralbronchus,with non uniform disrnses) ,apper lobe of right lung (4 cases) ,upper lobe of left lung (1 case). The CT findings included bilateral pulmonary dis seminated uneven nodular shadows (6 cases). Single mass like shadows (2 cases), lesions mainly with cavity (4 cases). patchy or larger confluent consolidation (5 cases) ,net like shadows (2 cases) ;enlarged mediastinal lymph nodes (3 cases), pleural effusion (1 cases). Appearance of "tree tree bud" on high resolution CT. Conclusion:Imaging manifestations in AIDS complicated with fungus chest infection were varied,which included lunge nodules with or without cavitates,patch or larger conlluent consolidation, attice litie snadows and tree bud signs. Once above mentioned appearances were observed, lung fungus infectiont should be considered.
