目的 探讨腮腺基底细胞腺瘤的 影像学表现。方法 回顾性分析15例经手 术及病理证实的腮腺基底细胞腺瘤的临床 特征、CT及MRI图像特点。结果 15例病灶 均为单发肿块，左侧7例，右侧8例；病灶 最大径为3.0cm，10例位于腮腺浅叶，5例 位于腮腺深叶；12例呈类圆形，3例呈椭 圆形；8例病灶呈实性，增强扫描病灶明 显强化，7例病灶伴有囊变，其中2例有壁 内结节，增强扫描壁内结节明显强化。结 论 腮腺基底细胞腺瘤好发于中老年人， 其影像学特征有利于术前诊断。

Objective To investigate the imaging features of basal cell adenoma of parotid gland. Methods The clinical features, CT and MRI features of 15 cases of parotid basal cell adenoma confirmed by surgery and pathology were analyzed retrospectively. Results 15 cases of lesions were solitary mass, 7 cases in the left, right side in 8 cases, the largest lesion diameter was 3.0 cm, 10 cases located in the superficial lobe of parotid gland, 5 cases were located in the deep lobe of the parotid gland; 12 cases were rounded, 3 were oval, 8 cases of lesions were solid, enhanced scan, the lesions were significantly enhanced, 7 cases with cystic lesions, including 2 cases with mural nodules, enhance scanning intramural nodules were significantly enhanced. Conclusion Basal cell adenoma of the parotid gland is good in the middle aged and the elderly, and its imaging features are good for preoperative diagnosis.
