彩色多普勒超声检查颈部早期恶性淋巴瘤

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.

Ultrasonic examination by color Doppler's method in the diagnosis of early cervical malignant lymphoma

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.
