Abstract: 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.
