高频超声检查对颈部囊性病变的诊断价值

目的分析颈部各类囊性病变的灰阶及彩色多普勒超声的图像表现,探讨高频超声的不同超声特征。方法分析107例各类颈部囊性病变的资料,并就灰阶及彩色多普勒超声的应用做了前瞻性研究,包括病灶内血流的丰富程度及分布方式、以及血流的各项指数测定。结果良性肿瘤性病变及类瘤样病变、恶性肿瘤的二维超声和彩色超声表现均有一定特点,多项血流指数测定无鉴别诊断价值。良性肿瘤性病变及类瘤样病变诊断正确率高,为91．1％（92／101）,恶性肿瘤病变（癌性囊肿）诊断准确率低,为16．7％（1／6例）。结论高频超声检查是颈部各类囊性病变简便有效的诊断方法,尤其对良性病变。

Value of high-resolution ultrasonography in differential diagnosis of cervical cystic lesions

Objective To analyze ultrasonographic features of the different kinds of cervical cystic lesions, and propose differential diagnostic standard for these lesions based on the evidence of high resolution ultrasonography. Methods The clinical data of 107 patients with different kinds of cervical cystic lesions were analyzed. The role of gray scale and colour Doppler sonography for such lesions was prospectively studied. Results The rate of accuracy for benign cervical cystic lesions was 91. 1% (92/101) , however, it was only 16.7% (1/6) for malignant cervical cystic lesions. Conclusion High-resolution ultrasonography is effective and simple in differential diagnosis of different kinds of cervical cystic lesions, especially for benign ones.
