艾滋病并发粟粒型肺结核的CT表现

目的：探讨艾滋病并发粟粒型肺结核的CT影像表现及临床特点,以提高肺部弥漫性粟粒性病变的临床影像诊断水平。方法：回顾性分析本院临床确诊的9例艾滋病并发粟粒型肺结核和42例单纯粟粒型肺结核的CT影像检查及临床相关资料,观察肺粟粒结节的大小、分布、密度、磨玻璃影、结节边缘征象等,以及观察纵隔淋巴结肿大、胸腔、心包积液的程度。结果：9例艾滋病伴粟粒型肺结核结节大小一致3例,分布均匀4例,密度均匀2例,磨玻璃影8例,结节边缘模糊6例,合并有纵隔淋巴结肿大6例,胸腔积液7例,心包积液5例,肺外结核6例。42例单纯粟粒型肺结核中,结节大小一致32例（76%）,结节分布均匀37例（80%）,密度均匀33例（78%）,磨玻璃影3例（7%）,结节边缘模糊8例（17%）,合并有纵隔淋巴结肿大12例（28%）,胸腔、心包积液11例（23%）。结论：艾滋病伴粟粒型肺结核与单纯粟粒型肺结核在结节分布、大小和密度、结节边缘征像以及合并纵隔淋巴结肿大、浆膜腔积液、肺外结核等方面差异有显著性意义（P〈0.05）。了解其相关临床影像表现特征有利于艾滋病并发肺结核的早期诊断和治疗。

CT Manifestations of Miliary Pulmonary Tuberculosis in AIDS Patients

Objective:To evaluate the computed tomography features on AIDS patients complicated with miliary pulmonary tuberculosis in order to improve the diagnosis of miliary lung diseases.Methods:9 AIDS patients complicated by miliary pulmonary tuberculosis and 42 patients with miliary tuberculosis alone were retrospectively reviewed and analyzed.Helical CT was performed to analyze the features of these patients including distribution,size,density and margin of miliary nodule as well as pericardial effusion,pleural ...
