摘要
目的:分析腮腺常见良性肿瘤的临床表现及CT表现,以提高其术前诊断准确率。资料与方法:回顾性分析45例经手术病理证实为腮腺良性肿瘤患者的临床资料及CT影像资料,结合文献并总结其临床及影像学表现特征。结果:45例患者中,形态规则,多形性腺瘤24例(均为单发),基底细胞腺瘤6例(均为单发),腺淋巴瘤15例(单发5例,多发10例,双侧多发5例)。10例腺淋巴瘤患者有长期吸烟史;多形性腺瘤表现为渐进性强化;基底细胞腺瘤表现为动脉期和静脉期显著强化,静脉期较动脉期稍减退;腺淋巴瘤表现为"快进快出",可有血管贴边征;三者增强方式不同,其强化差异有统计学意义(P<0.05)。结论:腮腺常见良性肿瘤具有一定CT特征表现,结合患者临床表现,有利于提高其术前诊断准确率。
Objective:To analyze the clinical and CT manifestations of common benign parotid gland tumors,so as to improve the preoperative diagnosis accuracy.Methods:Clinical data and CT imaging data of 45 patients with parotid gland benign tumor confirmed by surgery and pathology were retrospectively analyzed.Results:Among the 45 patients,there were 24 cases of pleomorphic adenoma(all single),6 cases of basal cell adenoma(all single),15 cases of adenoma(5 cases of single occurrence,10 cases of multiple occurrence,5 cases of bilateral multiple occurrence).Ten patients with adenocarcinoma had a long history of smoking.Pleomorphic adenoma presents progressive enhancement.Basal-cell adenoma showed significant enhancement in arterial stage and venous stage,and decreased slightly in venous stage compared with arterial stage.Adenocarcinoma presents as"fast in,fast out",and may have vascular border signs;3 patients had different enhancement methods,and the difference of enhancement was statistically significant(P<0.05).Conclusion:The common benign tumors of parotid gland have some CT features,which is helpful to improve the preoperative diagnosis accuracy.
