摘　　要：目的探讨螺旋CT(MSCT)增强检查联合临床资料在腮腺常见良性肿瘤诊断和鉴别诊断中的价值。方法回顾性分析经病理证实56例腮腺良性肿瘤,其中多形性腺瘤28例、腺淋巴瘤21例、基底细胞腺瘤7例,分析三者临床资料、形态学特征、强化特征及程度。结果多形性腺瘤、腺淋巴瘤、基底细胞瘤的平均年龄分别为(38.9±16.8,61.8±9.0,50.1±22.2)岁,多形性腺瘤发病年龄较轻,与腺淋巴瘤统计学意义(P<0.05);腺淋巴瘤在性别、吸烟、病灶数目方面均与另两者差异有统计学意义(P<0.05);多形性腺瘤、腺淋巴瘤、基底细胞瘤动脉期强化CT值分别为(61.9±23.0,109.1±19.6,96.9±28.9)HU、动脉期净强化值分别为(27.4±20.0,65.9±18.9,60.3±26.1)HU、静-动脉期强化差值分别为(9.8±7.8,-34.5±15.1,-13.9±14.5)HU,多形性腺瘤与后两者三者差异有统计学意义(P<0.05);腺淋巴瘤与基底细胞腺瘤在静-动脉期强化差值上差异有统计学意义(P<0.05)。结论MSCT增强检查对腮腺常见良性肿瘤诊断及鉴别诊断有重要价值,联合临床资料更有价值。Objective To discuss the value of spiral CT(MSCT)contrast-enhanced examination combined with clinical data in the diagnosis and differential diagnosis of common parotid benign tumors.Methods A total of 56 cases of benign parotid tumors confirmed by pathology,including 28 cases of parotid pleomorphic adenoma,21 cases of adenolymphoma,and 7 cases of basal cell adenoma,were analyzed retrospectively about clinical data,morphological characteristics,enhancement characteristics and degree.Results The mean ages of parotid pleomorphic adenoma,adenolymphoma and basal cell tumor were(38.9±16.8,61.8±9.0,50.1±22.2)years,and the age of onset of pleomorphic adenoma was younger,it was statistically significant with adenoma(P<0.05).There were significant differences in gender,smoking,and number of lesions between the two groups(P<0.05);Pleomorphic adenoma,adenolymphoma,basal cell tumor in arterial phase enhanced CT values were(61.9±23.0,109.1±19.6,96.9±28.9)HU,arterial phase net enhancement values were(27.4±20.0,65.9±18.9,60.3±26.1)HU,and the venousarterial phase enhancement difference were(9.8±7.8,-34.5±15.1,-13.9±14.5)HU,pleomorphic adenoma after the difference was statistically significant(P<0.05);The difference between adenolymphoma and basal cell adenoma in the venous-arterial phase was statistically significant(P<0.05).Conclusion MSCT enhanced examination have great value in the diagnosis and differential diagnosis of common benign parotid tumors.Combined with clinical data is more valuable.
