      CT diagnosis and differential diagnosis of parotid Warthin tumor

      摘要:
      目的:探讨腮腺Warthin瘤的CT表现,提高对本病的诊断及鉴别诊断水平.方法:回顾性分析32例手术病理证实的腮腺Warthin瘤的临床及影像资料.结果:32例腮腺Warthin瘤患者共发现肿块53个,单侧发病24例(75.0%),单侧多发4例;双侧发病8例(25.0%),双侧多发3例;肿块位于腮腺浅叶后下象限45个(84.9%),位于深叶3个(5.7%),跨浅叶及深叶5个(9.4%);肿块多为圆形及椭圆形共47个(88.7%),呈分叶状或不规则状肿块6个(11.3%),肿块多为囊实性.增强后实性成分呈“快进快出”表现,囊性成分不强化,囊性成分表现为囊腔样、分隔状及“裂隙”征.结论:腮腺Warthin瘤CT表现具有特征性,CT结合临床特点对病变定性诊断及鉴别诊断有一定价值.
      Abstract:
      Objective:The CT findings of parotid Warthin tumors were studied to improve the ability of diagnosis and differential diagnosis of this disease.Methods:The clinical materials and imaging data of 32 cases of parotid Warthin tumors confirmed by surgery and pathology were retrospectively analyzed.Results:There were totally 53 lesions in 32 cases,of which 24 cases(75.0%) with lesions in unilateral side and 8 cases(25.0%) with lesions in bilateral sides.Among it there were 4 cases with unilateral multiple lesions and 3 cases bilateral multiple lesions.Moreover,we found 45 lesions in the posterior inferior quadrant of superficial lobe(84.9%),5 lesions in the inter-leaves(9.4%),and 3 lesions in the deep lobe(5.7%).There are 47 lesions (88.7%) with round or oval shape and 6 lesions (11.3%) with lobulated or irregular shape.The tumors are mostly with both solid and cystic components.After enhancement the solid components manifested as "fast wash-in and fast washout" pattern;the cystic components had no enhancement and manifested as cystic or separated cavity and "fissure sign".Conclusion:The specific CT manifestations of parotid Warthin tumors combined with the clinical characteristics are useful for the qualitative diagnosis and differential diagnosis of this disease.
