腮腺Warthin瘤的影像学分析

目的:分析腮腺Warthin瘤CT、MRI影像学表现,提高对本病的认识。方法:回顾性分析经手术病理证实的37例腮腺Warthin瘤CT、MRI表现。其中男32例,女5例。年龄27～80岁,平均59岁,50岁以上26例(70.2%)。有吸烟史30例(81%)。结果:37例共56个病灶,单侧单发28例(28个病灶),单侧多发4例(12个病灶),双侧多发5例(16个病灶);CT及MRI表现:病灶长径0.5～4.8cm,呈圆形或椭圆形,边界清楚,内部密度或信号均匀或不均;CT增强扫描病灶实质部分呈早期明显强化,MRI增强扫描病灶呈不均匀强化。结论:腮腺Warthin瘤有一定的临床和CT、MRI特点,结合患者年龄、性别及病史,可提高对其诊断准确率,减少误诊。

The Imaging Analysis of Warthin Tumor of Parotid Gland

Objective： To investigate the findings of the CT and MRI of the warthin tumor of parotid gland, in order to improve its knowledge. Methods： The CT and MRI findings of 37 patients （32 males and 5 female, the age ranged from 27-80 years with average of 59 years） proved pathologically were retrospectively analyzed. 30 cases had history of smoking （81%）. Results： 56 lesions were found among 37 cases, with unilateral single tumors in 28 cases （28 lesions）, unilateral multiple lesions in 4 cases （12 lesions）, and bilateral multiple lesions in 5 cases （16 lesions）. The maximal diameter of the lesions ranged between 0.5 cm and 4.8 cm. The lesions were round or oval, and well-demarcated soft tissue mass. The parenchyma of the tumors appeared as homogeneous or heterogeneous density or signal intensity. The parenchyma of the lesions demonstrated early significant enhancement on postcontrast CT, and non-uniform enhancement on postcontrast MRI scans. Conclusion： There are some characteristic clinical and CT and MRI features in the warthin tumor, its diagnostic accurate rate can be improved combined with the patient＇s age, gender and the long duration of clinical symptoms.
