Abstract:
Objective To investigate CT image features of pleomorphic adenoma and adenolymphoma,and to improve the diagno-sis accuracy.Methods CT data of 1 3 cases of pleomorphic adenomas and 9 cases of adenolymphomas confirmed by pathology were retrospectively analyzed and compared.Results All 1 3 cases of pleomorphic adeonoma were solitary lesions,in which 1 1 cases were located in the non posterior inferior quadrant,and 1 1 cases showed persistent or delayed enhancement,with “slowly forward and slowly quit”enhancement performance.In all of the 9 cases of adenolymphoma,3 cases were multiple lesions.In total of 1 3 lesions, 9 lesions were located in the posterior inferior quadrant,and 9 lesions were significantly enhanced in the arterial phase and enhance-ment was decreased in the delayed phase,which showed “quickly forward and quickly quit”.Conclusion CT image features of pleo-morphic adenoma and adenolymphoma are different.Most of lesions can be diagnosed correctly before surgery by using image fea-tures with clinical information.
