【摘要】 [目的]探讨艾滋病(acquired immune deficiency syndrome,AIDS)合并纵隔淋巴结结核的临床及CT表现特点,以提高对其的认识。[方法]将26例AIDS合并纵隔淋巴结结核作为研究对象(简称合并组),26例无免疫损害的纵隔淋巴结结核作为对照组,对比分析两组的临床及影像学特点。[结果]AIDS合并纵隔淋巴结结核的临床特点:①结核菌素试验(PPD)阳性率,合并组7.7%,对照组73.1%,P=0.000,两组差异有统计学意义;②CD4+T淋巴细胞计数,合并组(6~108)×106/L,对照组(425~557)×106/L,t=55.75,P<0.001,两组差异有统计学意义。CT表现特点:①病变累及3~5组以上淋巴结,合并组20例,对照组6例,P=0.000,两组差异有统计学意义;②平扫淋巴结密度均匀,合并组4例,对照组15例,P=0.003,两组差异有统计学意义;③平扫淋巴结有低密度区,合并组20例,对照组10例,P=0.005,两组差异有统计学意义;④淋巴结有钙化,合并组2例,对照组12例,P=0.004,两组差异有统计学意义;⑤均匀强化,合并组4例,对照组15例,P=0.012,两组差异有统计学意义;⑥分格状强化,合并组16例,对照组6例,P=0.033,两组差异有统计学意义。[结论]AIDS合并纵隔淋巴结结核的临床及CT表现具有一定特点,有助于提示诊断。更多还原

【Abstract】 [Objective] To investigate the clinical and CT features of HIV(AIDS) with mediastinal lymph node tuberculosis, in order to raise awareness on it.[Methods] 26 cases of HIV(AIDS) combined mediastinal lymph node tuberculosis were collected as the study group and 26 cases of non-immune damage mediastinal lymph node tuberculosis as a control group, the clinical and radiological features comparative analysis was made between two groups. [Results] AIDS combined mediastinal lymph node tuberculosis clinical features: ① PPD-positive rate, the combined group 2 patients, in the control group of 19 patients, P =0.000 ≤0.05, the difference was statistically significant. ② CD4 +T lymphocyte count consolidated group(6 ~108) ×106/L, the control group(425 ~ 557) ×106/L, t= 55.75, P<0.001 ≤0.01, the difference was statistically significant. CT features: ① lesion involving more than 3 ~5 lymph nodes, combined group of 20 patients, 6 cases in the control group, P =0.000 ≤0.05, the difference was statistically significant; ② unenhanced lesions density, the combined group of four cases, 15 cases in the control group, P=0.003≤0.05, the difference was statistically significant; ③lesions unenhanced low-density areas, the combined group of 20 cases, 10 cases in the control group, P=0.005≤0.05, the difference was statistically significant; ④ calcified lesions combined group 2 patients, in the control group of 12 patients, P =0.004 ≤0.05, the difference was statistically significant; homogeneous enhancement; ⑤4 cases in combination group with control groups 15 cases, P=0.012 ≤0.05, the difference was statistically significant; ⑥ points trellis strengthen the combined group of 16 patients in the control group of six cases, P=0.033≤0.05, the difference was statistically significant. [Conclusion] The clinical and CT findings of combined mediastinal lymph node tuberculosis have some characteristics that will help prompt diagnosis of HIV(AIDS).更多还原
