摘　　要：目的探讨腮腺多形性腺瘤与腺淋巴瘤的CT影像特点，提高对两者的鉴别诊断能力。方法回顾性研究经手术病理证实的13例多形性腺瘤及9例腺淋巴瘤的CT表现，并做对比分析。结果13例多形性腺瘤均为单发，11例位于腮腺非后下象限，增强11例表现为持续性或延迟强化，呈“慢进慢出”改变；9例腺淋巴瘤3例多发共13个病灶，9个病灶位于腮腺后下象限，增强9个病灶动脉期显著强化，延迟期强化减退，呈“快进快出”表现。结论腮腺多形性腺瘤与腺淋巴瘤CT影像表现各有特点，掌握各自特征性影像表现并结合临床资料，绝大多数病灶术前可以做出正确诊断。Objective To investigate CT image features of pleomorphic adenoma and adenolymphoma,and to improve the diagno- sis accuracy.Methods CT data of 13 cases of pleomorphic adenomas and 9 cases of adenolymphomas confirmed by pathology were retrospectively analyzed and compared.Results All 13 cases of pleomorphic adeonoma were solitary lesions,in which 11 cases were located in the non posterior inferior quadrant, and 11 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 13 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.
