目的:探讨腮腺Warthin瘤的多层螺旋CT(multislice CT,MSCT)表现及病理改变。方法:回顾性分析经手术病理证实的21例腮腺Warthin瘤的临床资料及MSCT表现,并与病理结果相对照。所有病灶均行MSCT平扫及增强扫描。结果:病灶CT特征表现为腮腺浅叶后下极圆形、椭圆形肿块,平均最大径约2.2 cm,多数边缘光整,仅4个病灶边缘模糊,手术证实合并感染。12个病灶可见囊变、坏死,但均未见钙化;增强扫描肿瘤实体部分多呈明显或中度强化,均无延迟强化。21个病灶内见小血管通过或包绕,10个病灶呈“贴边血管征”。结论:腮腺Warthin瘤的MSCT表现具有一定的特征性,结合临床资料,有助于术前正确诊断及鉴别诊断。
Objective: To investigate the manifestation and pathological changes of multislice CT (MSCT) in parotid Warthin tumor. Methods: The clinical data and MSCT findings of 21 cases of parotid Warthin tumor proved by surgery and pathology were retrospectively analyzed. The results were compared with the pathological findings. All lesions were MSCT plain scan and enhanced scan. Results: The CT features of parotid gland showed the shape of lower circular and oval tumor. The average maximum diameter was about 2.2 cm. Most of the margins were smooth and only 4 lesions were fuzzy. Operation confirmed the infection. 12 lesions showed cystic degeneration, necrosis, but no calcification; enhanced solid tumors were mostly obvious or moderate enhancement, no delay enhancement. See 21 small vessels within the lesion through or around the 10 lesions were Conclusion: The MSCT findings of parotid Warthin tumor have some characteristics. Combined with clinical data, it is helpful to diagnose and differentiate preoperatively.
