Abstract
目的探讨CT平扫在腮腺Warthin瘤诊断及鉴别诊断中的价值。方法对23例经手术病理证实的腮腺Warthin瘤病人CT平扫特征进行回顾性分析。结果 23例病人共检出51个病灶,单侧单发5例,单侧多发6例共13个病灶,双侧多发12例共33个病灶,病灶多发者占病人的78.26%。病灶位于腮腺浅叶上区5个,腮腺浅叶下区32个,腮腺深叶上区4个,腮腺深叶下区10个,位于腮腺下区者占病变总数的82.30%。42个病灶表现为密度较均匀的圆形、类圆形、结节样或浅分叶状包块,边界光滑,CT值18~64Hu。9个病灶见囊变,边界模糊,其中囊变伴坏死3例,囊变伴出血2例。2例病人同时行增强CT检查,均表现为均匀强化,CT值较平扫增加约30Hu。有9例病人出现反应性淋巴结增生。结论腮腺Warthin瘤CT平扫的特征性表现对本病的诊断有一定的意义。
