艾滋病患者感染性病变的淋巴结影像表现分析

目的 探讨艾滋病（AIDS）患者感染性病变的淋巴结影像表现。方法收集AIDS患者的临床及影像数据，选取经活检取材，病理确诊的AIDS感染性病变165例，包括结核、肺孢子菌肺炎、马尔尼菲蓝状菌、隐球菌、巨细胞病毒感染等，对其淋巴结影像表现进行对比分析。结果对纵隔淋巴结肿大的统计，结核最明显（97.8%），其次是马尔尼菲蓝状菌（95.2%）、肺孢子菌肺炎（40.0%）、隐球菌（32%）；对淋巴结见低密度改变的统计，结核最明显（50%），其次是马尔尼菲蓝状菌（27.5%）。结核与马尔尼菲蓝状菌感染，淋巴结CT征象差异有统计学意义的是淋巴结低密度改变和环状强化（P＜0.05）。结论AIDS感染性病变的淋巴结影像表现具有一定特征性，结合其肺部影像表现对鉴别诊断有所帮助。

The CT findings oflymphadenopathy in patients with AIDS

Objective To study theCT imaging features of lymphadenopathy in patients with AIDS. Methods Theclinical and imaging data of AIDS patients from January 2016 to December 2019were collected. The cases included tuberculosis, Talaromyces marneffei,pneumoeystis pneumonia, cytomegalovirus, and cryptococcosis. ResultsTuberculous lymphadenopathy was most pronounced in tuberculous (97.8%, 44/45),and followed with Talaromyces marneffei (95.2%, 40/42), pneumocystis pneumonia(40.0%, 14/35), and cryptococcosis (32%, 8/25). CT lymph node signs werestatistically significant different in low density changes of lymph nodes andring enhancement (P<0.05). Conclusion The lymph node imaging findingsof AIDS infective lesions have certain characteristics. Combined with itspulmonary imaging findings, it is helpful for differential diagnosis.
