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。

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 wash-out” 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.
