干燥综合征腮腺的超声表现

目的评价干燥综合征的腮腺超声检查价值。方法分析42例干燥综合征患者的腮腺的声像图特点。结果根据干燥综合征腮腺的大小、实质内有无结节及团块、结节的数量、腮腺的血流分布特点将声像图分为4型：①类正常型：腺体大小回声基本正常，彩色血流信号强度多为0级；②结节型；腺体内呈弥漫性分布的低回声结节，彩色血流信号强度1～2级；③团块型：腺体内见低回声或混合性回声团块，彩色血流信号强度1～2级，血流的分布形式以团块的“周边环绕型”和“内部分支型”为主；④萎缩型：腺体体积缩小，可伴主导管扩张及囊肿形成。彩色血流信号强度多为1级。结论腮腺的超声检查在于燥综合征的诊断及鉴别诊断中是一种有价值的检查方法。

Ultrasonic appearances of parotid with Sjogren's syndrome

Objective To evaluate the value of ultrasonography for parotid with Sjogren＇ s syndrome. Methods Parotid of 42 patients with Sjogren＇ s syndrome were examined by ultrasonography, then their sonograms were analyzed retrospectively. Results According to the size of parotids, nodules and masses appearance in parenchyma, distribution of blood flow and peripheral lymph nodes. the sonograms were divided into four types： ①Quasinormales type： the size and echo of parotid were normal, the most intensity of color blood flow signal was mostly grade 0. ②Nodules type： diffuse low level echo nodule were detected in parotid, and the intensity of color blood flow signal was grade 1 - 2.③Lump type：low level echo or mix echo lump were detected in parotid, and the intensity of color blood flow signal was grade 1 - 2, the blood distribution were most of around and inside it. ④Atrophy type; the volume of parotids became smaller with main duetal ectasia and cyst formation, the intensity of color blood flow signal was mostly grade 1. Conclusion Uhrasanography plays an important role in diagnosis and differential diagnosis of parotid with Sjogren＇ s syndrome.
