摘要
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.
