摘　　要：目的探讨颈颌面部Kimura病(Kimura’s disease,KD)的CT表现,提高对该病的诊断水平。资料与方法回顾性分析7例经病理证实的颈颌面部KD的临床及CT表现。7例患者均为男性,平均年龄30.8岁,病程较长。临床表现为颈颌面部无痛性肿块,所有患者血嗜酸性粒细胞均明显增多。结果 CT上有三种表现:(1)多发结节型3例,位于涎腺或颈部间隙内,表现为多发结节,边界清晰,增强扫描呈明显均匀强化;(2)弥漫肿块型3例,常位于颌面部皮下脂肪间隙内,表现为皮下弥漫性肿块,边界模糊,邻近皮肤增厚,增强扫描呈轻中度不均匀强化;(3)混合型1例,同时具有结节及肿块特点。多数患者(6/7)伴有颈部淋巴结肿大。结论 KD有一定的临床和CT特点,结合实验室检查,可提高对其的诊断准确率。Objective To investigate the CT findings of Kimura disease（KD） in neck and maxillafacial region in order to improve its diagnosis.Materials and Methods The clinical and CT findings of 7 cases with KD in neck and maxillafacial region were retrospectively analyzed.All seven patients were male,with a mean age of 30.8 years.7 cases with KD had long clinical courses,with asymptomatic swelling in the neck and maxillafacial region.All 7 cases had the rise of blood eosinophilia.Results All the masses seen in the present case series could be classified into the three following morphological patterns：Type 1（n=3）,demonstrate mutiple nodulor,which were relatively well-defined,nodular masses with homogeneous enhancement.They were usually seen in the major salivary glands.Type 2（n=3）,demonstrate diffuse masses,which were ill-defined,plaque-like in configuration,and heterogeneous in appearance with variable enhancement.Type 3（n=1）,display overlaps between both the type 1 and type 2 lesions.Regional lymph nodes enlarged was noted in 6/7 cases.Conclusion There are some characteristic clinical and CT findings in Kimura disease,its diagnostic accurate rate can be improved combined with the laboratory examination.
