【摘要】 目的探讨多层螺旋CT在腮腺多形性腺瘤诊断中的价值。方法回顾性分析我院2014年至2016年经手术及病理学证实的腮腺多形性腺瘤患者20例,总结其CT影像学特点,并结合文献资料,进一步提高多层螺旋CT对腮腺多形性腺瘤的诊断准确率。结果 20例患者共发现26个病灶,其中19例为单侧、单发病灶,一例为单侧多发病灶,5例病灶有浅分叶,15例密度较均匀,5例密度不均匀伴有囊变;平扫最高密度为41.6HU,最低密度为26.7HU,平均36.1HU;增强扫描观察8例病灶呈较均匀强化,12例呈不均匀强化。结论腮腺多形性腺瘤在CT图像上具有一定的特征性,多层螺旋CT平扫及增强扫描在腮腺多形性腺瘤诊断中具有很高的诊断和鉴别诊断价值。更多还原

【Abstract】 Objective To study multislice CT value in the diagnosis of parotid pleomorphic adenoma.Methods Retrospective analysis of 2014 to 2016,confirmed by surgery and pathology of 20 cases of parotid pleomorphic adenoma patients,summarize the CT imaging characteristics,combined with the literature data,further increase of multislice CT in the diagnosis of parotid pleomorphic adenoma accuracy.Results A total of 20 patients found 26 lesions,19 cases of unilateral and single lesion.l case is unilateral multiple lesions.5 cases with shallow lobe.15 cases of density is uniform,15 cases with uneven density of capsule.Scan the highest density of 41.6 HU,the minimum density of 26.7HU,an average of 36.1 HU.Enhanced scanning are uniformly 8 cases of reinforcement,12 cases of non-uniform reinforcement.Conclusion Multislice CT scan and enhanced scan in parotid pleomorphic adenoma diagnosis are of great value in diagnosis and differential diagnosis.更多还原
