摘　　要：目的探讨腮腺Warthin瘤的CT影像表现特征。方法回顾性分析经手术病理证实的21例腮腺Warthin瘤的临床及CT影像特点,对病变的部位、形态、大小、数目、CT平扫和双期增强表现进行分析。结果 21例腮腺War-thin瘤患者,共43个病灶,双侧多发2例,单侧多发6例,83.7%(36/43)病灶或病灶主体位于腮腺浅叶后下极;40个病灶呈圆形或类椭圆形;97.7%(42/43)病灶边缘清楚。CT平扫83.7%(36/43)病灶密度均匀。增强扫描,病灶呈均匀或不均匀强化,动脉期病灶实性部分呈中度-明显强化,增强幅度(45.6±15.7)HU;静脉期强化减退,增强幅度(28.5±10.3)HU;74.4%(32/43)病灶可见包绕血管/或小血管进入病灶。结论腮腺Warthin瘤的CT表现具有一定特征性,结合临床特点有助于作出定性诊断。Objective To study the CT performance characteristics of parotid Warthin tumor. Methods CT imaging fea- tures of parotid Warthin tumor confirmed by operation and pathology were retrospectively analyzed in 21 cases. Location, shape, size, number, CT plan scan and dual-phase enhancement characteristics of the lesions were analyzed. Results 43 lesions were found in 21 cases, among them bilateral multiple lesions were found in 2 cases and unilateral multiple lesions in 6 cases. 83.7% （36/43）lesions located at the back and lower of the superficial lobe. Shapes of 40 lesions were round or oval. 97.7% （42/43）lesions showed clear boundary. 83.7%（36/43）lesions were homogeneous density in plan scan. All lesions showed homogeneous or heterogeneous enhancement. Solid part of lesions showed moderate to marked enhance- ment in arterial phase. Enhanced amplitude （comparing with plan scan） was （45. 6~ 15.7） HU. The density was de- creased in vein phase, Enhanced amplitude（comparing with plan scan） was （28.5± 10.3） HU. Small blood vessels sur- rounded or pricked the lesions in 74.4% （32/43） lesions. Conclusion The CT manifestations of parotid Warthin tumor has certain characteristics. CT manifestations combined with clinical features can contribute to make a qualitative diagno
