Abstract: Objective To investigate the ultrasonographie characteristics of basal cell adenoma in salivary gland and to improve the coincidence of ultrasound diagnosis for the tumor. Methods The ultrasonographic 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 ultrasonography and clinical information is conducive to differentiate basal cell adenoma and pleomorphic adenoma of salivary gland.
