目的：探讨分析腮腺多形性腺瘤和腺淋巴瘤的C T特点。方法收集手术病理证实的多形性腺瘤31例(男14例，女17例，年龄在16-78岁，平均年龄49.39)和腺淋巴瘤20例（男19例，女1例，年龄在43-80岁，平均年龄62.1），对有术前C T的19例多形性腺瘤（19个病灶）和15例腺淋巴瘤（19个病灶）的C T特点进行对照分析。结果腮腺多形性腺瘤实质成分动脉期大多（13/19）呈轻度强化，静脉期强化程度均呈持续上升，上升幅度在（13±7） H u，腺淋巴瘤实质成分动脉期均呈中度或明显强化，静脉期强化程度均呈下降趋势，下降幅度在（14±10）H u。结论双期增强C T扫描对腮腺多形性腺瘤和腺淋巴瘤的鉴别具有重要意义，腮腺多形性腺瘤增强曲线以缓慢上升为主，而腺淋巴瘤则主要表现为“快进快出”。

Objective To analyze the CT characteristics of plemorphic adenoma and adenolymphoma in the parotid gland. 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 col ected. 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 (13±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 (14±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 manifested in the quick rising and fal ing.
