摘要
目的:探讨腮腺孤立性实性占位的MRI表现及特征。资料与方法:回顾性分析我院2013年1月1日—2018年1月1日的88例诊断腮腺孤立实性占位并经病理证实患者的MRI影像资料,通过观察病灶的部位、大小、形态、数目、信号特点及强化方式,比较其MRI诊断符合率及鉴别要点。结果:88例孤立实性占位病变,良性肿瘤71例,恶性肿瘤14例,肿瘤样病变3例。74例良性病变中,混合瘤及腺淋巴瘤在发生位置、同血管密切程度及T2WI信号差异方面具有统计学意义(P<0.05)。混合瘤与血管关系不紧密,腺淋巴瘤绝大多数靠近血管,与其关系密切,差别具有统计学意义(P<0.05)。恶性肿瘤在形态、边界、T2WI信号及间接征象与良性肿瘤差异有统计学意义(P<0.05)。结论:MRI对于腮腺孤立性占位的良恶性诊断及混合瘤与腺淋巴瘤的诊断具有具有较高的价值。
Objective Investigate the MRI features of solitary solid parotid mass.Materials and Methods Reviewing MRI images of 88 patients with pathologically diagnosed solitary solid parotid mass from Jan. 1 st 2013 to Jan. 1 st in our hospital, We compared the the diagnostic accordance rate of MRI diagnosis and tried to find differential points in MRI diagnosis.diby observing the location, size, shape, number, signal characteristics and enhancement mode of the lesions.Results Among the 88 solitary solid space-occupying lesions mentioned above, 71 cases were benign tumors, 14 cases were malignant tumors, and 3 cases were tumor-like lesions. In 74 cases of benign tumor or tumor-like lesion, there were statistically significant defferences between mixed tumor and adenolymphoma in location, degree of homovascularity and T2WI signal(P < 0.05)There were significant differences between malignant tumor and benign tumor in shape, boundary, T2WI signal and indirect signs.(P < 0.05).Conclusion MRI is of great significance in diagnosing benign and malignant solitary solid parotid mass and distinguishing mixed tumor andadenolymphoma.
