多排螺旋CT对腮腺肿瘤的诊断价值（附13例报告）

摘要

目的：提高对腮腺肿瘤的CT诊断与鉴别诊断水平。方法回顾性分析13例腮腺肿瘤的CT表现和病理结果。结果腮腺混合瘤10例(共18个病灶)，黏液表皮样癌1例，非霍奇金淋巴瘤1例，嗜酸性淋巴肉芽肿瘤1例。结论 CT征象可以为腮腺肿瘤的良恶性鉴别诊断提供有价值的依据，位于浅叶、边界清楚、类圆形或椭圆形的腮腺肿瘤多为良性肿瘤；反之，多为恶性肿瘤。%Objective To raise the level of diagnosis and differential diagnosis of parotid tumors.Methods The CT findings of 13 parotid tumors were retrospectively analyzed.Results 10 cases of parotid mixed tumor with 18 lesions, mucoepidermoid carcinoma in 1 case, non-Hodgkin's lymphoma in 1 case, eosinophilic lymphoid granuloma in 1 case.Conclusion CT imaging is can provide valuable basis on the benign and malignant differential diagnosis of parotid tumors. A parotid tumor located in the superficial lobe, with a round or oval contour and sharp margin, is more likely to be a benign tumor. Otherwise, it might be a malignant tumor.
