目的：探讨腮腺基底细胞腺瘤的 CT 特征。方法回顾分析6例经手术及病理证实的腮腺基底细胞腺瘤的CT 图像，重点评价肿瘤的部位、大小、形态、边缘、密度及强化特征。结果6例均为单发肿块，4例位于腮腺深叶，2例位于浅叶；6个肿瘤均呈圆形，无分叶，边界清晰；肿瘤内部均可见囊变区，其中2例表现为大囊伴壁结节。增强扫描动脉期，肿块实性部分呈显著强化，静脉期密度略有下降。结论腮腺浅叶孤立性结节，边界清晰，内见坏死囊变或呈大囊＋壁结节，动脉期实性部分显著强化，静脉期 CT 值略有下降，应考虑腮腺 BCA 的可能。

Objective To investigate the CT features of basal cell adenoma of the parotid gland .Methods CT features of basal cell adenoma in 6 patients confirmed by operation and pathology were reviewed retrospectively .All CT images were retrospectively evaluated with respect to location ,size ,morphology ,margin ,density and enhancement features .Re‐sults All of the 6 cases were single tumor ,4 cases were located in the deep lobe and 2 cases in the shallow lobes .All the 6 tumors were clear boundary and round shape without lobular appearance .Cystic degeneration was displayed in all the 6 cases ,2 lesions were shown cystic areas in the center with wall nodules ,the solid part of the tumor was significantly en‐hanced in arterial phase ,and slightly decreased in venous phase .Conclusion Solitary nodule located in the shallow lobe of parotid gland ,clear boundary and necrosis in variable or a large capsule together with wall nodules ,and CT value in‐creased significantly in arterial phase and slightly decreased in venous phase should be considered the possibility of basal cell adenoma .
