摘要
目的探讨彩色多普勒超声检查颈部早期恶性淋巴瘤的价值。方法分析12例(57个淋巴结)颈部恶性淋巴瘤的超声二维图像、彩色多普勒及频谱的特征、分布的部位及结外病变。结果颈部淋巴结肿大,长径与短径比值(L/S)<2;8例内部为低回声,4例低回声内部出现液性暗区,皮质非均匀增宽(46/57),髓质结构紊乱变窄或呈线状(42/57);CDFI显示(49/57)淋巴结血流信号丰富呈不规则的树枝状或紊乱,呈点状周边有血流信号包绕(8/57);淋巴结血流速度增加,阻力指数较高。结论应用彩色多普勒超声检查颈部肿大的淋巴结,可对颈部恶性淋巴瘤临床早期诊断提供一定的诊断依据。。
Objective To evaluate the diagnostic value of ultrasonic examination by color Doppler＇s method in early cervical malignant lymphoma. Methods Fifty-seven lymph nodes from 12 patients with cervical malignant lymphoma were studied by their 2D ultrasonic images, color Doppler and frequency spectra, locations and ex-lymph node diseases. Results The cervical lymph nodes manifested swelling, L/S〈2, interior low echo-level（8/57）, fluid dark area within low echo-level（4/57）, non-uniform widening of cortex（46/57）, confused structure of medulla with narrowing or linear shape（42/57）, abundant blood flow signal showing irregular arborization or disorder（49/57） or punctiform image surrounded by blood flow（8/57） under CDFI, increased blood flow and higher drag index. Conclusion Examination of swelling cervical lymph nodes by color Doppler＇s ultrasonic method may provide early diagnostic evidence for cervical malignant lymphoma.
