摘要：

目的：回顾性分析31例经术后病理证实的腮腺基底细胞瘤MSCT扫描影像特征，探讨MSCT在腮腺基底细胞瘤的影像诊断价值。方法：搜集31例经手术病理证实的腮腺基底细胞瘤的MSCT检查资料，所有病例术前均进行CT平扫和双期增强扫描。评价肿瘤平扫和增强特征，包括增强程度和方式。结果：基底细胞瘤平扫呈不均匀的等密度结节，可见比较明显的囊变区；增强动、静脉期均显著强化，动脉期CT值增加幅度与混合瘤有显著差别，具有统计学差异(P＜001)，与腺淋巴瘤比较没有显著差别(P＞005)，静脉期CT值增加幅度与腺淋巴瘤、混合瘤比较有统计学差异(P＜001)。结论：腮腺基底细胞瘤具备良性肿瘤的特征，CT增强特征为动脉期和静脉期呈较显著的持续性强化，伴有显著的囊变。

To review MSCT imaging features of 31 cases of basal cell tumor and explore its diagnostic value of MSCT.Methods:31 patients with pathologically confirmed basal cell tumor underwent the preoperative MSCT plain\|scan and dual\|phases scanThe change of CT value and enhancement patterns were assessed in these tumors.Results:Basal cell tumors showed isodense nodule with significant cystic area on CT plain\|scanAt dual\|phase scan,basal cell tumors showed a pattern of persistent strong enhancement with characteristic cystic areasAt arterial phase,the increase of CT value was the highest for basal cell tumors,which was significantly statistical difference with pleomorphic adenoma(P＜001)At veouse phase,the increase of CT value was statistically different between basal cell tumor and other two histopathologic types(P＜005).Conclusions:Basal cell tumors showed hetergenouse isodense nodule on CT plain\|scan,which showed a pattern of persistent strong enhancement with characteristic cystic areas
