【摘要】 目的探讨腮腺腺淋巴瘤(Warthin瘤)的CT、MRI影像学表现。方法回顾性分析经手术及活检病理证实的12例腮腺Warthin氏瘤的CT、MRI的影像学表现。结果12例腮腺Warthin瘤均为单侧发病,男性10例,女性2例,50岁以上8例(66.7%)。单发9例,多发3例,共16个病灶,其中9个(56.3%)病灶位于腮腺后下方。病灶呈圆形、椭圆形及分叶状软组织肿块,边缘光整,密度均匀或不均匀,囊变区呈类圆形液性密度灶;MRIT1WI病灶呈低信号,脂肪抑制T2WI呈高信号,囊变区呈更长T1、长T2信号,大多表现为早期轻中度强化。结论根据腮腺Warthin瘤的发病年龄、性别、部位及影像学表现,有助于该病诊断和鉴别诊断。更多还原

【Abstract】 Objective:To discuss the CT and MRI findings of Warthin′s tumor in parotid gland.Methods:12 patients had pathology proven Warthin′s tumor in the parotid gland,CT and MRI findings were retrospectively analysed.Results:Of the 12 cases,there were male （n=10）,female （n=2）,8 patients （66.7%） were over 50 years of age.Altogether there were 16 lesions,with solitary （n=9）,multiple （n=3）.All lesions were located unilaterally,with the mass located in the lower-posterior part of the gland （n=9,56.3%）.On CT and MRI,lesions were round、oval or lobulated in shape,well-defined,homogeneous or heterogeneous soft tissue mass.Cystic area showed round shape and liquid density.On MRI,lesions were hypointense on T₁WI,while hyterintense on T₂WI with fat suppress sequences,cystic area showed long T₁、T₂ signal intensities.After contrast administration,most of the lesion showed early mild or moderate enhancement on CT or MRI.Conclusion:Clinical materials including age,gender,location and imaging manifestations of lesion plays a helpful role in the diagnosis and differential diagnosis of Warthin′s tumor.更多还原
