腮腺腺淋巴瘤的CT表现
Radiologic Practice(2008)
Abstract
目的:探讨腮腺腺淋巴瘤的CT和临床表现特点.方法:回顾性分析经手术及病理学证实的12例腮腺淋巴瘤的CT表现,主要观察病灶大小、数目、形态、位置及其密度.结果:12例腮腺腺淋巴瘤患者均为男性,7例病灶单发,5例多发(其中3例为双侧腮腺腺淋巴瘤),共21个病灶,其中13个(61.9%)病灶位于腮腺后下象限;CT表现病灶呈类圆形、椭圆形及分叶状软组织肿块,边界清,密度均匀(12个)或不均,CT增强扫描病灶实性部分CT值增高10~65 HU,其中13个(61.9%)病灶内见小血管通过或包绕.结论:年龄50岁以上男性患者,CT表现腮腺浅叶后下象限病灶,边界清,强化明显,特别是多发病灶和(或)病灶内见小血管进入时应首先考虑腮腺腺淋巴瘤可能.
