Abstract：Objective To investigate the CT features of pleomorphic adenoma and Warthin tumor of parotid so as to improve the differential diagnosis of two lesions .Methods The CT features of 58 cases, including 22 cases of pleomorphic adenoma with 23 masses and 25 cases of Warthin tumor with 35 masses, which were verified by operation and pathology , were retrospectively an-alyzed in this work .Results All of those 58 tumors appeared to be round or oval well-defined, hyperdensity mass .The differ-ences among the age of onset of both , position, plain CT value, the comparison of the density with ipsilateral masseter muscle , the CT value after enhancement , net enhancement CT value , the maximum transverse diameter , and vertical diameter ratio had statis-tical significance .Conclusion As for the differential diagnosis of benign tumors in parotid gland , if the tumor occurs in the older men and lower quadrants , with moderate or made enhancement , and has close relationship with the surrounding blood vessels , and inhibits the oval mass , then, the diagnosis of Warthin tumor in parotid gland is strongly suggested .
