摘要
目的分析腮腺Warthin瘤的CT特征与病理基础,以期术前能够作出正确诊断。方法收集腮腺Warthin瘤患者19例(22个病灶),均经手术、病理证实,并于术前行CT平扫+双期增强扫描,分析其CT特征,观察病变的位置、数目、形态、境界、密度、强化方式及强化程度、有无贴边血管征。结果19例共22个病灶,单侧多发1例(2个病灶),双侧单发2例;位于浅叶19个,非浅叶(跨/深叶)3个,15个病变位于浅叶后下极;20个病变形态规整(类圆形/圆形);20个病变境界清楚,包膜完整;14个病变呈实性,8个病变内见不同程度囊变,呈囊实性;实性成分于动脉期多呈中度或显著强化,静脉期强化减退,表现为“快进快退”;12个病变周围或者内部可见血管包绕、穿行,即“贴边血管征”。结论腮腺Warthin瘤具有一定的CT及临床特征,综合分析可作出较好地诊断和鉴别诊断。
Objective To make a correct diagnosis preoperatively by analyzing CT features and pathological basis of parotid Warthin tumor.Methods Nineteen patients(22 lesions)with Warthin tumor of parotid gland were collected,all of them confirmed by surgery and pathology;preoperative CT plain scan and dual-phase enhanced scan were performed to analyze the CT features and observe the lesion′s location,number,morphology,boundary,density,enhancement mode and degree,and whether there was welt vascular sign.Results There were totally 22 lesions in 19 patients,of which 1 case with unilateral multiple lesions and 2 cases with bilateral single lesions;nineteen lesions located in the superficial lobe and 3 lesions located in non-shallow(cross/deep)lobes;15 lesions located behind and below the superficial lobe of parotid gland;20 lesions with regular shape and 20 lesions with clear boundary and intact capsule;14 lesions were solid and 8 lesions were cystic and solid;in the arterial phase,most of the solid components show moderate or significant enhancement,while in the venous phase,the enhancement decreases,presenting as“fast forward and fast backward”;peripheral or internal vessels can be seen around 12 lesions,that was“welt vascular sign”.Conclusion Warthin tumor of parotid gland has certain CT and clinical characteristics,and comprehensive analysis can make better diagnosis and differential diagnosis.
