艾滋病颈部非霍奇金淋巴瘤CT表现

CT manifestations of cervical non Hodgkin lymphoma in AIDS

目的探讨艾滋病颈部非霍奇金淋巴瘤(NHL)的CT表现。方法搜集2014年1月至2017年6月南宁市第四人民医院艾滋病颈部NHL患者10例作为观察组,搜集同期广西医科大学第一附属医院非艾滋病患者颈部NHL患者20例作为对照组,对比分析艾滋病与非艾滋病颈部NHL的CT表现。结果艾滋病合并颈部NHL患者病变淋巴结最大径[(6.88±3.19)cm]较非艾滋病颈部NHL患者大[(4.33±2.33)cm],差异具有统计学意义(t=2.495,P=0.019),两组患者病变淋巴结CT密度、边界差异具有统计学意义(Fisher精确检验,P=0.019、0.045),淋巴结融合(Fisher精确检验,P=1.000)、增强扫描强化方式(χ^2=1.069,P=0.586)差异无统计学意义。结论艾滋病患者颈部NHL病变淋巴结常较大且坏死多见,通常预后较差。

Objective To investigate CT findings of cervical Non-Hodgkin’s lymphoma (NHL) in AIDS patients. Methods To collect 10 cases of NHL in the cervical of AIDS patients in Nanning Fourth People's Hospital from January 2014 to June 2017 as observation group, and 20 cases of NHL in the cervical of non-AIDS patients in the First Affiliated Hospital of Guangxi Medical University were collected as control group. Results The maximum diameter of lymph nodes in AIDS patients with cervical NHL (6.88 ±3.19 )cm was larger than that of non AIDS patients with cervical NHL (4.33 ±2.33 )cm, and the difference was statistically significant (t = 2.495, P = 0.019). The difference of lymph node density and boundary between the two groups was statistically significant (Fisher exact test, P = 0.019,0.045). Lymph node fusion (Fisher exact test, P = 1.000) and enhanced scan enhancement (χ^2= 1.069, P = 0.586) were not statistically significant. Conclusion The diameter of lymph nodes of AIDS combined with cervical NHL was usually larger (6.88 ±3.19 )cm and more necrotic, and usually AIDS patients have poor prognosis.
