摘要

目的：

探讨腮腺混合瘤与腮腺腺淋巴瘤的磁共振成像（magnetic resonance imaging，MRI）表现特征，提高对两者的诊断正确率。

方法：

收集中国人民解放军联勤保障部队第九〇九医院20152018年经手术后病理学检查证实的26例腮腺混合瘤与42例腺淋巴瘤的临床资料并分析总结其MRI影像学特征，包括病灶数目、形态、信号及强化特点。

结果：

混合瘤发病以中青年为主，男女性别差异不大，而腺淋巴瘤发病以中老年为主，且明显以男性多见；混合瘤多单发（26例），腺淋巴瘤可多发（42例患者中11例多发，其中9例双侧多发，2例单侧多发），混合瘤T2WI上信号多混杂，呈渐进性强化，而腺淋巴瘤多囊变，增强早期明显强化，延迟快速廓清。

结论：

腮腺混合瘤及腺淋巴瘤的MRI表现有一定的特征，结合患者的性别及发病特点，可明显提高两者的诊断准确率。

Abstract

Objective:

To improve the diagnostic accuracy between parotid gland mixed tumor and parotid gland adenolymphoma by comparing their features on magnetic resonance imaging (MRI).

Methods:

The clinical data of 26 cases of parotid gland mixed tumor and 42 cases of parotid gland adenolymphoma were collected from 2015 to 2018 in 909th Hospital of the Joint Logistics Support Force of PLA. The features of MRI imaging

include lesion number

morphology

signal and enhancement

were retrospectively analyzed.

Results:

With epidemiology

the incidence rate of the parotid gland adenolymphoma in male is si

gnificantly higher than that of female aging rang from middle-aged and old age. But there is no difference between the mixed tumor

aging rang from young and middle-aged age. According to MRI images

We found that the mixed tumor was generally single (all of 26 cases)

but the parotid gland adenolymphoma can be multiple (11 case of 46 cases). In addition

the mixed tumor was usually progressive enhancement and the mixed signal

but the parotid gland adenolymphoma was significantly enhanced in the early stage and then delayed rapidly.

Conclusion:

The MRI features of the mixed tumor and adenolymphoma of the parotid gland have certain characteristics

which can improve the diagnostic accuracy of the two.
