摘　　要：目的:探讨CT对腮腺腺淋巴瘤的论断价值。方法:收集经手术病理证实的13例腺淋巴瘤患者的CT特点,分析病灶部位、数目、形态、大小、密度以及强化程度。结果:13例患者中位于单侧单发9例,单侧多发2例,双侧多发1例。居浅叶8例,深浅叶同时受累3例,深叶1例;肿瘤均呈圆形或类圆形,病灶最大径1.6～4.8cm,平均2.5cm。密度均匀4例,密度不均8例,伴囊性变者3例,增强后实性部分均有不同程度强化。结论:对于年龄>50岁的男性患者,腮腺后下极出现单发或多发无痛性肿块,边界清晰,内部密度均匀或不均匀,增强后实性部分早期明显强化,可考虑为腮腺腺淋巴瘤可能。Objective： To investigate the characteristics of CT manifestations of parotid adenolymphomas. Methods： 13 patients of parotid adenolymphomas proved by surgery and pathology were collected. The analysis of imaging characteristics included the position, number, shape, size, density and enhancement intensity. Results：In 13 cases of parotid adenolymphomas, 9 cases were found in unilateral side and solitary lesion, 2 cases in unilateral side and muti-lesions; 1 ease in bilateral side. 8 cases located in superfieial of parotid, 3 cases in superficial and deep of parotid, 1 case in deep lesions, lesions were round or oval, maximun diameter from 1.6 cm to 4.8 cm, average 2.5 cm , homogeneous density 4 eases and inhomogeneous 8 cases, cystic degeneration 3 eases. Lesions showed homogeneous enhancement except the area of cystic parts. Condusion：Adenolymphomas of the parotid should be first considered when the male patient over 50 years has lesions located in the posterior and inferior quadrant and with well defined margin, homogeneous density or inhomogeneous, especially earlier period obviously enhancement in part of lesions.
