Methods 31 cases of pleomorphic adenoma（male 14，female 17，aged 16-78 years old，mean age 49.39 years old） and 20 cases of adenolymphoma（male 19， female 1，aged 43-80 years old， mean age 62.1 years old）, confirmed by operation and pathology, were collected. To analyze the CT features of 19 cases of pleomorphic adenoma(19 lesions) and 15 cases of adenolymphoma(19 lesions），which were performed Enhanced CT scanning before operation. Results The solid portion of parotid pleomorphic adenoma were mostly slightly enhanced in arterial phase. Degree of enhancement in venous phase were continued to rise，rise in (13plusmn;7) Hu. The solid portion of adenolymphoma in arterial phase were obvious or moderate enhancement. In venous phase, enhanced degree showed a downward trend, dropped in (14plusmn;10) Hu. Conclusion Dual-phase enhanced CT scan has important significance on the identification of parotid pleomorphic adenoma and adenolymphoma，the enhanced curves of pleomorphic adenoma of parotid are mainly rising slowly，and the curves of adenolymphoma are mainly
