目 的 探讨腮腺腺淋巴瘤 (Warthin瘤)的MSCT表现与临床分析，以 提高对该瘤的诊断水平。方法 回顾性分 析经手术病理证实的29例腮腺Warthin瘤 的MSCT表现，并与行细针吸取细胞学检查 的14例进行比较，分析MSCT的诊断价值。 结果 29例患者中男25例；单侧单发22 例，双侧单发2例，单侧多发4例，双侧多 发1例，共45个病灶，其中75.6%(34/45) 病灶位于腮腺浅叶后下极。MSCT平扫4 例，25例行增强扫描动脉期，6个病灶轻 度强化，12个中度强化，23个明显强化， 其中22例诊断为Warthin瘤。14例细针 吸取细胞学检查中诊断Warthin瘤的有10 例，1例诊断为炎症，2例诊断为囊性病 变，1例诊断为恶性可能性大。结论 MSCT 增强扫描对腮腺Warthin瘤的诊断价值 与细针吸取细胞学检查相当，临床考虑 Warthin瘤的患者可依据MSCT表现进行手 术方案的选择。

Objective To investigate the MSCT features and clinical analysis of Warthin tumor in parotid gland, so as to improve the diagnostic accuracy. Methods Twenty-nine cases with parotid Warthin tumor with MSCT scanning were analyzed retrospectively, which were confirmed by operation and histopathology. The diagnostic accuracy of MSCT was compared with fine needle biography. Results In all of the 29 (male 25) cases, 22 cases were solitary lesions in unilateral, 2 cases were solitary lesions in bilateral, and 5 cases were multiple lesions, in which 4 cases were unilateral. Of all 45 lesions, 75.6% (34/45) lesions were located in the posterior and inferior quadrant. Four cases were nonenhancement MSCT scan, 25 cases were enhancement MSCT scan, 6 cases showed light enhancement, 12 cases median enhancement, and 23 cases showed prominent enhancement in arterial phase. 22 cases were diagnosed of Warthin tumor. A total of 14 cases were performed with fine needle aspiration cytology, 4 cases was not diagnosed with Warthin tumor. Conclusion The diagnostic value of MSCT in Warthin tumor of parotid gland was similar with fine needle aspiration cytology. Contrast-enhanced CT scan providing sufficient information of Warthin tumor in parotid gland, is useful in preoperation evaluation.
