摘要
目的研究腮腺基底细胞腺瘤的声像图特点，提高超声对该病的诊断符合率。方法对经手术病理证实的31例腮腺基底细胞腺瘤患者的声像图特点，结合病理学特征进行回顾性综合分析，并与腮腺多形性腺瘤进行鉴别分析。结果基底细胞腺瘤内部呈实质低回声，分布均匀，部分实质内可出现液化，后方回声增强，形态规则，边界清晰，硬度中等，彩色多普勒显示肿瘤内部或周边部有血流信号。结论基底细胞腺瘤的声像图依据其病理基础有一定特征性，超声检查结合临床表现有助于与多形性腺瘤鉴别。
Objective To investigate the uhrasonographic characteristics of basal cell adenoma in salivary gland and to improve the coincidence of ultrasound diagnosis for the tumor. Methods The uhrasonographic characteristics for 31 cases of basal cell adenoma which were pathologically confirmed were analyzed and summarized combining with its pathological characteristics retrospectively. A differential diagnosis between basal cell adenoma and pleomorphic adenoma was also made. Results Basal cell adenomas of salivary gland showed low and equivalent internal echoes, sometimes with colliquation in their substantial component. They showed enhanced posterior echo, middle hardness, clear boundary and regular shape. Color Doppler flow signals were also found in the center or periphery of the tumors. Conclusions The ultrasonic manifestation of the basal cell adenoma has its own characteristics, which is complied with its pathological basis. The combination of uitrasonography and clinical information is conducive to differentiate basal cell adenoma and pleomorphic adenoma of salivary gland.
