目的：??探讨腮腺少见肿瘤增强CT表现特征与病理的相关性，以提高影像诊断水平。方法??对22例经手术病理证实的少见腮腺肿瘤进行回顾性分析，包括基底细胞瘤6例，肌细胞上皮瘤5例，脉管瘤4例，淋巴上皮囊肿及腮腺脂肪瘤各3例，软骨肉瘤1例。在增强CT图像上，从病变所在腮腺的位置、病变大小和形态、病变密度以及其与周围结构的关系进行总结分析。结果??基底细胞瘤发生在腮腺浅叶，边界清楚，病变内易囊变。增强扫描呈不均匀中度-明显强化肿块，边缘或内部可见结节状强化，可伴有增大的淋巴结。肌细胞上皮瘤多发于腮腺浅叶，易发生小囊变，少数病变内可有小点状钙化。实性部分增强后中度-明显强化，多有典型的动脉期强化结节和边缘显著强化。血管瘤为软组织肿块，病变较大可占据整个腮腺，密度均匀或不均匀，可见静脉石，突出于腮腺表面，增强后轻度-明显强化。淋巴上皮囊肿囊液较黏稠，CT值密度较高。软骨肉瘤以囊性为主的肿块，含边缘钙化、骨化成分的肿块。腮腺脂肪瘤可见脂肪密度肿块，边界清晰，无强化，病变内可见纤维分隔。结论??腮腺少见肿瘤的增强CT表现具有一定的影像学特征，可揭示其病理基础；增强CT是诊断腮腺少见肿瘤病变性质有效的影像检查手段。
