艾滋病患者颈部包块的超声表现

The Ultrasonographic Manifestations of Cervical Mass in Patients with AIDS

目的:探讨艾滋病患者颈部包块的超声声像图特征。材料和方法:对21例艾滋病患者颈部包块行超声检查并结合临床资料分析其图像特征。结果:(1)超声表现:21例病例中有20例的超声表现为淋巴结肿大。其中,16例≥3cm的淋巴结/融合团块内可见大片无回声区,其内见细小点状回声漂浮,探头加压后见细小点状回声移动,彩色多普勒超声表现为尚存的实性回声部分可探及较多的红蓝彩色血流信号。(2)临床诊断:16例为淋巴结结核,2例为真菌感染,2例为化脓性细菌感染,1例病理符合坏死组织之改变,培养未见真菌、细菌,病因学未明。结论:艾滋病患者颈部包块淋巴结炎可能性大,其声像图表现具有一定特征。

Purpose： The aim of this study was to investigate the uhrasonographic characteristics of the cervical masses of AIDS patients. Materials and Methods： 21 cases of AIDS patients with cervical mass were studied using ultrasound and the uhrasonographic characters were compared with their clinical information. Results： （ 1 ）enlargement of lymph nodes were found in 20/21 cases. 16 cases had mass ≥ 3cm of fused lymph nodes with large anechoic area and floating echogenic dots inside. Color Doppler sonography demonstrated rich blood flow signal in the remaining parts of the mass; （2）16 cases were finally proved to have lymphoid tuberculosis, 2 cases of mycotic infection,2 cases pyogenic bacterial infection, and 1 case necrotic tissue of unknown etiology. Conclusion： The most cervical masses of AIDS patients were enlarged lymph nodes resulting from inflammation, which had certain uhrasonographic characteristics.
