颈部淋巴结结核的彩色多普勒超声表现

Color Doppler Ultrasonographic Findings of Cervical Tuberculous Lymphadenitis

目的 :分析颈部淋巴结结核 (CTBL)的彩色多普勒超声特点。方法 :回顾分析 10 5例经手术证实的CTBL 的病例资料 ,对其彩色多普勒超声表现进行分析、讨论。结果 :CTBL 好发于颈中及颈上组 (占 6 3.30 % )。所有病例均为多个淋巴结同时受累 ,87.6 2 %的病例有融合。病变中最大淋巴结二维声像图表现为匀质型 (2 .5 4 % )、粗大光点型 (11.0 2 % )、网状结构型 (12 .71% )及混杂型 (73.73% )。彩色多普勒能量图 (CDPI)表现为门部血流型 (2 4 .5 8% )、周边血流型 (2 7.97% )、混合血流型 (41.5 2 % )及无血流型 (5 .93% )。结论 :彩色多普勒超声是能清晰的显示CTBL 病变的数目、部位、形态特征 ,其超声表现较具特征性 ,正确认识其超声表现能提高本病的准确性。

Objective To analyse the Color Doppler Ultrasonographic findings of cervical tuberculous lymphadenitis(CTBL).Methods The Color Doppler Ultrasonographic findings and clinical materials of 105 patients with CTBL proved by surgery were analysed retrospectively.Result In 63.30 % of cases, the supra and mid-cervical lymph nodes were incolved by CTBL.More than one lymph nodes were affected in all cases and 87.62 % of cases had the matted phenomenon. The bigger lymph node were classified into 4 types according to the two-dimensional findings: TypeⅠ:even low echo (2.54 %) ; TypeⅡ: the thick and big spots (11.02 % ); Type Ⅲ:net-like (12.71 %); Type Ⅳ:mixed echo (73.73 %). The Color Doppler Power Imaging (CDPI) showed lymph node door vascularity (24.58 %),peripheral vascularity(27.97 %),the mixed vascularity (41.52 %)and no vascularity(5.93 %).Conclusion Color Doppler Ultrasound can demonstrate well the number, location and appearance characteristic of CTBL,its manifestations on Ultrasonography are typical and characeristic ,accurate understanding of these Ultrasonographic manifestations are helpful to raise the accuracy of ultrasonic diagnosis for this disease.
