摘 要:目的探讨艾滋病相关性肺部空洞病变的CT表现。方法回顾性分析经病理证实的85例艾滋病相关性肺部空洞病变患者的全肺CT扫描资料,7l例行病灶处HRCT扫描,总结不同病原菌感染导致肺部空洞病变的CT征象,不同疾病间cT征象的比较使用)(2检验。结果85例艾滋病相关性肺部空洞病变的CT表现:(1)肺结核28例:病灶位于上叶27例,单发空洞15例、多发空洞13例、不规则空洞18例,出现钙化灶8例、引流支气管影8例、卫星灶21例、支气管扩张6例、周边条索影13例、胸膜受累10例、淋巴结肿大10例。病灶位于上叶、出现钙化灶、引流支气管影、卫星灶、周边条索影及胸膜受累6种征象在肺结核与非肺结核之间的差异有统计学意义(x2值分别为12.535、26.753、13.944、17.978、11.362、7.796,P值均〈0.01)。(2)非结核分枝杆菌肺病6例:病灶位于上叶5例,单发空洞5例、厚壁空洞3例、外壁毛糙6例,出现卫星灶4例、支气管扩张3例。支气管扩张征象在非结核分枝杆菌肺病与非非结核分枝杆菌肺病之间的差异有统计学意义(x2=9.092,P〈0.01);卫星灶征象在非结核分枝杆菌肺病和肺脓肿、肺真菌病之间的差异有统计学意义(X2值分别为6.785、9.423,P值均〈0.01)。(3)肺脓肿12例:多发空洞9例,病灶〉4cm7例,厚壁空洞9例,外壁毛糙8例,内壁光滑11例,空洞内见液一气平面4例。多发空洞、病灶〉4cm及空洞内液一气平面3种征象在肺脓肿与非肺脓肿之间的差异有统计学意义(x2值分别为10.390、4.551、7.635,P值均〈0.05)。(4)肺真菌病39例;单发空洞33例、规则空洞25例,内壁光滑28例,出现壁结节7例,晕征10例,淋巴结肿大11例。单发空洞征象在肺真菌病与非肺真菌病之间的差异有统计学意义(X2=11.251,P〈0.01)。结论分析空洞的分布、�Objective To evaluate CT findings of cavitary puhnonary diseases in AIDS. Methods CT findings of cavitary pulmonary diseases were retrospectively analyzed in 85 patients with AIDS. Seventy- one of the patients were scanned by HRCT. The CT features of various infectious diseases were summarized and their signs were compared by Chi-square test. Results CT findings of cavitary pulmonary diseases in 85 patients with AIDS included : ( 1 ) pulmonary tuberculosis in 28 patients, with lesions in upper lung lobes (27 patients), single cavity ( 15 patients), multiple cavities ( 13 patients ), irregular cavity ( 18 patients ), calcification( 8 patients ), communication with bronchia ( 8 patients ), satellite lesions ( 21 patients ) , bronehieetasis (6 patients) , surrounding cord ( 13 patients), pleural involvement ( 10 patients ), and lymphadenopathy ( 10 patients). Tuberculous cavity in AIDS is closely related to the following CT findings: the focus in upper lung lobes, calcification, communication with bronchia, satellite lesions, surrounding cord and pleural involvement (P 〈 0. 01 ). (2) Non-tuberculous mycobacterial pulmonary infection in 6 patients with the lesions in the upper lung lobes (5 patients ), single cavity (5 patients ), thick-walled cavity ( 3 patients ), rough outer wall ( 6 patients ), satellite lesions ( 4 patients ), and bronchiectasis ( 3 patients). Non-tuberculous mycobacterial cavity in AIDS is closely related to CT finging of bronchiectasis (P 〈 0. 01 ). There was significant difference of satellite lesions between non-tuberculous mycobacterialpulmonary infection and pulmonary abscess and pulmonary mycosis (P 〈 0. 01 ). (3) pulmonary abscess in 12 patients with multiple cavities (9 patients), the size of more than 4 cm (7 patients), thick-walled cavity (9 patients), rough outer wall( 8 patients), smooth inner wall (11 patients), and air-fluid level inside the cavity (4 patient
