 ; 目的：探讨腮腺多形性腺瘤与腺淋巴瘤的CT特征及鉴别诊断; 以期提高诊断水平。方法：回顾性分析经病理证实的16例腮腺多形性腺瘤与7例腮腺腺淋巴瘤的CT表现及临床资料。结果：多形性腺瘤组：多发于中年; 位于腮腺浅叶中上极; 多呈类圆形; 边界清楚; 密度均匀或不均匀伴囊变坏死; 偶可见钙化; 增强扫描呈渐进性强化; 部分有供血动脉; 动态增强延迟期大部分病灶强化范围扩大; 腺淋巴瘤组：多发生于老年男性; 位于腮腺浅叶下极; 多呈类圆形; 边界清楚; 密度均匀或不均匀伴囊变坏死; 增强扫描多呈“快进快出”表现; 病灶均有供血动脉; 动态增强扫描延迟期病灶强化范围无扩大。两组患者在性别、年龄、病灶部位、数量、增强扫描CT值、供血动脉、增强后强化范围扩大比较; 两组具有显著性差异（P<; 0.05）; 吸烟史、病灶大小、密度比较无显著性差异（P>; 0.05）。结论：腮腺多形性腺瘤与腺淋巴瘤的CT表现有一定的特征性; CT增强扫描对两者的诊断及鉴别诊断具有很高的价值。

Abstract:
Abstract: Objective To investigate the CT features of pleomorphic adenoma and adenolymphoma of the parotid gland and its differential diagnostic values for improving the accuracy of diagnosis. Methods The CT findings and clinical data of 16 cases of pleomorphic adenoma of the parotid gland and 7 cases of adenolymphoma of the parotid gland were analyzed retrospectively. Results The pleomorphic adenoma mostly occurred in middle age and located in the middle and upper part of the superficial parotid gland. Most of them were round with clear boundary and showed uniform or uneven density with cystic degeneration, necrosis and even calcification. After dynamic contrast-enhanced scanning, they showed progressive enhancement. Part of lesions had blood supply arteries, and the enhancement ranges of most lesions were enlarged on delayed phase. The adenolymphoma mostly occurred in elderly male patients and located in the lower part of the superficial parotid gland. Most of them were round with clear boundary and showed uniform or uneven density with cystic degeneration and necrosis. The dynamic contrast-enhanced scanning showed "fast forward and fast out". All lesions had blood supply arteries, and the enhancement ranges of most lesions were not enlarged on delayed phase. Significant differences were found in gender, age, lesion location, number of lesions, contrast-enhanced CT values, blood supply arteries and enhanced ranges between the two groups (P<0.05). However, there was no significant difference in smoking history, lesion size and density between the two groups (P>0.05). Conclusion The CT features of pleomorphic adenoma and adenolymphoma of the parotid gland are characteristic. Therefore, enhanced CT scanning is of great value in the differential diagnosis of pleomorphic adenoma and adenolymphoma in the parotid gland.
