Warthin瘤MRI诊断的再认识(附13例分析)

Revaluation of MRI in diagnosis of Warthin tumor( a report of 13 cases)

目的探讨Warthin瘤的MRI表现特征并结合相关文献加以分析,以提高对本病的认识。方法收集2006年6月-2013年6月我院及南京军区南京总医院共13例经病理证实的Warthin瘤患者临床和影像资料进行回顾性分析。结果 13例Warthin瘤患者中,男11例,女2例;7例单发,6例多发,共21个病灶;病灶呈圆形或类圆形14个,类椭圆4个,分叶状2个,哑铃状1个;21个病灶位于后下部16个,5个病灶位于腮腺其它部位;病灶边缘在FSE T1WI上可见低信号环,在FSE T2WI脂肪抑制序列上呈等或稍高信号;在FSE T1WI上增强扫描病灶呈轻-中度强化。结论 Warthin瘤MRI表现具有一定的特征及好发部位,术前MRI检查不但可以对肿瘤进行定位,而且还可以定性,为临床制定正确的手术方案具有一定的指导意义。

Objective To revaluate the diagnostic value of MRI in Warthin tumor in combination with related literature in order to improve our understanding .Methods Clinical data and MRI findings of 13 patients with pathologically proved War-thin tumor were observed from June 2006 to June 2013 and analyzed retrospectively .Results Among the 13 patients,11 were male and 2 were female .A total of 21 lesions included 7 cases with solitary mass ,and 6 cases with multiple mass .These lesions were round or nearly round in shape in 14,oval in 4,lobular in 2 and dumbbell shape in 1.Of the 21 lesions,16 were located in the posterior and inferior quadrant of the parotid ,and 5 in the other quadrants .All lesions had slightly low signal on FSE T1WI,and slight hyperintensity or isointensity on FSE T 2WI fat suppress.Most lesions showed mild or moderate enhancement after contrast administration on FSE T1WI.Conclusin MRI is valuable in locating the tumor,helpful in differentiating benign from malignant ,and also has certain guiding significance in selecting reasonable surgical treatment scheme .
