【摘要】：目的：探討并分析頸部結核性淋巴結與轉移性淋巴結在超聲聲像圖中的特點。方法：回顧性分析獲得病理結果的105例患者的160個淋巴結,其中結核性淋巴結76個,轉移性淋巴結84個。對照分析兩組淋巴結下列超聲表現(xiàn)：L/S、邊界、淋巴門、內(nèi)部回聲、鈣化、壞死液化,分析其特點。結果：兩組內(nèi)部均可呈現(xiàn)鈣化和液性無回聲區(qū)。而轉移性淋巴結內(nèi)部鈣化多為微鈣化,呈簇狀分布,結核性淋巴結內(nèi)多為散在粗鈣化,兩者間差異有統(tǒng)計學意義(P0.01)。轉移性淋巴結內(nèi)部液化區(qū)多偏心分布且面積比50%,結核性淋巴結內(nèi)液化區(qū)多位于中央且面積比50%,兩者間差異有統(tǒng)計學意義(P0.01)。結論：鈣化的大小與分布、液化區(qū)的位置與面積比等超聲影像學特點有助于鑒別頸部結核性淋巴結與轉移性淋巴結。
[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.
