目的：探讨CT对各类腮腺肿瘤的诊断及鉴别诊断价值。方法回顾性分析本院2008年5月~2014年2月78例经手术及病理确诊腮腺肿瘤 CT图像，包括肿瘤的大小、密度、形态、边缘、有无钙化及囊变、强化特点等。结果78例腮腺肿瘤均为单侧、单发病灶。其中混合瘤、淋巴乳头状囊腺瘤、基底细胞腺瘤及肌上皮瘤多表现为类圆形或团块影，边界清晰，密度均匀且高于正常腮腺，增强扫描多呈均匀强化。其中钙化多见于混合瘤，囊变多见于淋巴乳头状囊腺瘤、基底细胞腺瘤。粘液表皮样癌、肌上皮癌病灶多呈分叶状，边界欠清晰，密度不均匀且高于正常腮腺，增强扫描不均匀强化。酸性淋巴肉芽肿、淋巴上皮性病变多呈弥漫性肿大，密度不均匀，边界欠清，增强扫描可见明显不均匀强化。两侧腮腺对称性受累多发生于淋巴上皮病。结论各类型的腮腺肿瘤在CT图像上具有各自的影像学特点，依靠其 CT表现，能够予以诊断及鉴别诊断，具有重要的临床应用价值。

Objective To investigate the CT diagnosis and dif erential diagnosis of various types of parotid tumors. Methods A retrospective analysis of our hospital from May 2008 to February 2014 during the 78 cases confirmed by surgery and pathology parotid tumor CT images, including tumor size, density , shape, edge , with or without calcification and cystic degeneration , and other enhanced features . Results 78 cases of parotid tumors are unilateral , single lesion . Which mixed tumor , lymph papil ary cystadenoma , basal cel adenoma and myoepithelioma more performance for round or mass shadow , clear boundaries, uniform density and higher than normal parotid gland , enhanced scan mostly homogeneous enhancement .Which is more common in mixed tumor calcification , common in the lymphatic cystic papil ary cystadenoma , basal cel adenoma. Mucoepidermoid carcinoma , myoepithelial carcinoma lesions mostly lobulated borders unclear , uneven density and higher than normal parotid gland , enhanced scan heterogeneous enhancement . Acidic lymphogranuloma , lymphatic epithelial lesions mostly dif use enlargement , uneven density , less clear boundaries , enhanced scan showed obvious heterogeneous enhancement . Symmetry on both sides of the parotid gland involvement occurs in the lymph epithelial disease. Conclusion The various types of parotid tumors on CT images with their imaging features , relying on its CT manifestations, diagnosis and dif erential diagnosis can be , has important clinical value.
