腮腺Warthin瘤与腮腺多形性腺瘤的超声对照分析

摘要

Objective To explore the ultrasound characteristics of parotid Warthin's tumor and parotid pleomorphic adenoma.Methods Ultrasound characteristics were analyzed in 20 cases of parotid Warthin's tumor and 24 cases of parotid pleomorphic adenoma.Results Of the 20 cases ( 24 tumors) of parotid Warthin's Tumor, considered, 2 were with bilateral single tumors, 1 was with unilateral multiple tumors; integral capsules were found for all the 24 tumors, tumors originated from the lower posterior polar of the parotid gland in 18 cases; echoes turned out to be hypoechoic in 15 cases, while solid and mixed type echoes were detected in 6 cases and 14 cases respectively.All 24 cases of pleomorphic adenomas turned out to be unilateral witha single tumor, with 15 of them originated from the superficial lobe of the parotid gland and the other 9 located in the deep lobe; integral capsules were noticed in 20 of the 24 cases; the tumors turned out to be lobulated in 9 cases; solid homogeneous hypoe-choic echoes were detected in 6 cases, solid heterogeneous hypoechoic echoes were detected in 12 cases, the other 6 cases were characterized by mixed echoes.Color Doppler results indicated more abundant blood supply in parotid Warthin's tumors than in pleomorphic adenomas.Conclusion Parotid Warthin's tumor and parotid pleomorphic adenoma show different ultrasound characteristics, which may assist the differentiation diagnosis between them.%目的 探讨腮腺Warthin瘤与腮腺多形性腺瘤的超声鉴别要点.方法 对20例腮腺Warthin瘤和24例腮腺多形性腺瘤在超声特征方面进行总结分析.结果 20例腮腺Warthin瘤肿瘤个数共24个,2例双侧单发,1例一侧多发,一侧单发,包膜均完整;18例位于腮腺后下极,15例呈弱低回声;实质性回声6例,混合性回声14例.24例腮腺多形性腺瘤均单侧单发,15例位于腮腺浅叶,9例位于腮腺深叶;包膜完整20例,不完整4例;9例呈分叶状,实性均匀低回声6例,实性不均匀低回声12例,混合性回声6例.彩色多普勒示腮腺Warthin瘤较多形性腺瘤血供丰富.结论 腮腺Warthin瘤与多形性腺瘤在超声特征方面有各自的规律,根据它们的规律性并与临床特点相结合,可以帮助鉴别这两种腮腺肿瘤.
