【摘要】：目的：探讨并分析颈部结核性淋巴结与转移性淋巴结在超声声像图中的特点。方法：回顾性分析获得病理结果的105例患者的160个淋巴结,其中结核性淋巴结76个,转移性淋巴结84个。对照分析两组淋巴结下列超声表现：L/S、边界、淋巴门、内部回声、钙化、坏死液化,分析其特点。结果：两组内部均可呈现钙化和液性无回声区。而转移性淋巴结内部钙化多为微钙化,呈簇状分布,结核性淋巴结内多为散在粗钙化,两者间差异有统计学意义(P0.01)。转移性淋巴结内部液化区多偏心分布且面积比50%,结核性淋巴结内液化区多位于中央且面积比50%,两者间差异有统计学意义(P0.01)。结论：钙化的大小与分布、液化区的位置与面积比等超声影像学特点有助于鉴别颈部结核性淋巴结与转移性淋巴结。
[Abstract]:Objective: to investigate and analyze the characteristics of tuberculous lymph nodes and metastatic lymph nodes in ultrasonography. Methods: 160 lymph nodes of 105 patients were analyzed retrospectively, including 76 tuberculous lymph nodes and 84 metastatic lymph nodes. The following ultrasound findings of the lymph nodes in the two groups were analyzed as follows:% L / S, boundary, lymphoid hilum, internal echo, calcification, necrosis and liquefaction. Results: both groups presented calcification and liquid anechoic region. But the internal calcification of metastatic lymph nodes was mostly microcalcification with cluster distribution and the tuberculous lymph nodes were mostly scattered in coarse calcification. The difference between them was statistically significant (P0.01). The internal liquefaction area of metastatic lymph node was more eccentric and the area was 50% than that of tuberculous lymph node. The liquefaction area of tuberculous lymph node was located in the center and the area ratio was 50. The difference between them was statistically significant (P0.01). Conclusion: the size and distribution of calcification and the ratio of location to area of liquefaction are helpful to distinguish tuberculous and metastatic lymph nodes.
