摘要
目的研究腮腺腺淋巴瘤的临床及MRI特点。方法回顾分析经手术及病理证实的腮腺腺淋巴瘤17例共21个病灶的MRI特点。结果17例患者中单发14例,多发3例。其中男性15例,女性2例,平均年龄64.5岁。21个病灶中14个位于腮腺下后极。T1WI上20个病灶为等、稍低信号,局部见更低信号,1例病灶为高信号;T2WI上13个病灶表现等、低信号,7个病灶表现稍高信号,1个病灶表现为稍低信号。增强扫描19个病灶均有不同程度不均匀强化,强化程度为等于或稍高于正常腮腺。结论腮腺腺淋巴瘤MRI有一定特点,结合临床资料应能正确诊断。
Objective To investigate the characteristics of MR appearance of adenolymphoma in parotid gland. Methods The characteristics of MRI appearance of 17 cases with Warthin tumors were confirmed by operation and pathology were reviewed retrospectively. Results For all 17 patients, 15 of them were men and 2 were women . The average age of patients was 64.5 years old. Fourteen of 17 cases with adenolymphoma had solitary focus and 3 cases had multiple focus. The total of 21 focus were detected. Fourteen focus located in the inferior pole of parofid gland. Twenty focus demonstrated iso to slightly hypointensity, one focus showed hyperintensity on T1WI. Thirteen focus showed iso to hypointensity and one low signal intensity on T2WI. on postcontrast images, 19 focus displayed inhomogeneous enhancement, the signal intensity equal to normal parofid gland or higher than that of parotid gland. Conclusion The adenolymphoma of parofid gland have characteristic appearance on MRI, combining the clinical data can make correct diagnosis.
