摘　　要：目的 探讨不同部位木村病的CT及MRI表现.方法 收集本院经病理证实19例木村病患者的CT和MRI行回顾性分析,并结合文献讨论.结果 19例木村病中累及头颈部16例、肺内1例、胸壁1例、肝脾受累1例.头颈部木村病CT表现为结节、团块及弥漫性密度异常,平扫与肌肉密度相似,T1WI呈等或稍低信号,T2WI呈高信号,CT和MRI增强扫描多为中度或明显强化.肺内及胸壁木村病表现为软组织肿块,增强扫描肺内病灶呈中度强化,胸壁病灶呈环形强化.肝脾同时受累木村病病灶呈散在结节状轻度强化灶.结论 木村病影像学表现缺乏特征性,需结合实验室检查及病理综合判断.Objective To explore the CT and MRI findings of Kimura disease in different location.Methods The CT and MRI obtained in 19 patients with histologically proved Kimura disease were reviewed retrospectively.Results Of these 19 patients with Kimura disease, the head and neck was involved in 16 patients, other locations less commonly involved were the lung（n=1）,chest wall（n=1）,liver and spleen（n=1）.Kimura disease of head and neck,the density abnormal appeared as nodular,mass or diffuse on CT imaging, the CT value of lesion was similar to muscle, MRI manifested as a slightly hypo-or isointense lesion on T1WI and hyperintense on T2WI,most of the lesions demonstrated moderate or marked enhancement on postcontrast CT and MR images.Kimura disease of lung and chest wall,lesion appeared as a solid mass on imaging, there was moderate enhancement in the lung lesion and rim enhancement in the chest wall lesion.Kimura disease of liver and spleen： lesion showed nodular, mild and gradual upward enhancement.Conclusion Imaging findings of Kimura disease are not characteristic, it is very essential to know the lesion combined with the laboratory and pathologic features.
