Basal cell adenoma is a rare benign salivary gland epithelial tumor, usually involving the parotid gland. We report CT and MR findings of three cases with basal cell adenoma occurring in the parotid gland. The three cases presented here demonstrate a well-circumscribed tumor, which showed a cystic and solid, or the pure solid mass. They were well enhanced after contrast matter injection. The solid portion of the mass was isoattenuated at CT, with intermediate signal intensity on T1- and T2-weighted MR images. Its cystic portion was hyperintense on both T1- and T2-weighted MR images. It had a hypointense rim on T2-weighted image.
基底细胞腺瘤是一种罕见的涎腺良性上皮性肿瘤,通常累及腮腺。我们报告3例发生于腮腺的基底细胞腺瘤的CT和MR表现。本文报告的3例均表现为边界清晰的肿瘤,呈囊实性或纯实性肿块。增强扫描后强化明显。肿块实性部分在CT上呈等密度,在T1加权和T2加权MR图像上呈中等信号强度。其囊性部分在T1加权和T2加权MR图像上均呈高信号。在T2加权图像上有低信号环。
