超声对腮腺多灶性病变的诊断价值

The Diagnostic Value of Ultrasound in Multifocal Lesions of the Parotid Gland

目的探讨超声对腮腺多灶性病变良恶性的鉴别诊断价值。方法回顾性分析59例行超声检查发现腮腺多灶性病变的患者,以病理为“金标准”,记录患者的性别、年龄、病灶的数目、分布位置、腺体内淋巴结和最大病灶的大小、形状、物理性质、实性部分“网格状”形态、纵横比、边界、后方回声改变、血流情况。结果59例病变中,良性50例,恶性9例。恶性病变患者的中位年龄为41岁,超声多表现不规则和“粗网格状”;良性病变患者的中位年龄为57岁,超声多表现为规则和“细网格状”。良恶性病变在年龄、形状及实性部分“网格状”形态均有统计学差异(P<0.05)。其余指标在良恶性鉴别中均无统计学差异(P>0.05)。结论腮腺多灶性病变的超声表现具有一定特征性,超声对良恶性病变的鉴别具有较高的诊断价值。

Objective To investigate the value of ultrasound in the differential diagnosis of benign and malignant parotid multifocal lesions.Methods A retrospective analysis of 59 patients with multifocal lesions of the parotid gland found by ultrasound was performed.Taking pathology as the"gold standard",the gender,age,number and distribution of lesions,lymph nodes in the gland and the size,shape,physical properties,"grid-like"morphology of solid parts,aspect ratio,boundaries,posterior acoustic change,blood flow of the largest lesion were recorded.Results Among the 59 lesions,50 were benign and 9 were malignant.Patients with malignant lesions,with a median age of 41 years,were mostly irregular and"coarse grid"on ultrasound;patients with benign lesions,with a median age of 57 years,were mostly regular and"fine grid"on ultrasound.The benign and malignant lesions were significantly different in age,shape and"grid-like"shape of the solid part(P<0.05).There was no statistical difference in the other indicators in the differentiation of benign and malignant(P>0.05).Conclusion The ultrasound manifestations of multifocal lesions of the parotid gland have certain characteristics,and ultrasound has a high diagnostic value in the identification of benign and malignant lesions.
