一半以上AIDS病人有胸部受累,主要是各种机遇性感染和AIDS相关的肿瘤所致。由于机体T细胞免疫功能严重缺陷,同一种疾病在AIDS和非AIDS病人中常有不同的影像学表现。另一方面,由于前者机体处于不同的免疫抑制状态以及多种开发症的同时存在,导致其影像学表现复杂多样,特异征象不多。密切结合临床资料及穿刺活检有助于确诊。 More than half of AIDS patients have chest involvement, mainly due to various opportunistic infections and AIDS-related tumors. Because of the severe defects of T cell immune function, the same kind of disease often has different imaging findings in AIDS and non-AIDS patients. On the other hand, due to the fact that the former organism is in different immunosuppressive states and multiple developmental complications exist simultaneously, their imaging manifestations are complex and diverse with few specific signs. Closely combined with clinical data and biopsy can help diagnose.
