Kimura's disease is a rare disease of the head and neck region affecting mainly the adult males in eastern countries. The parotid and periparotid subcutaneous regions are the most common sites in head and neck region. Coupled with peripheral eosinophilia and raised serum IgE levels as characteristic features on hemogram, a painless swelling in parotid and periparotid region is diagnostic of Kimura's disease. Magnetic resonance imaging (MRI) has been an important modality in evaluating lesions of the head and neck region. Recently, interest in the diffusion weighted imaging (DWI) and contrast enhanced MRI (CEMRI) imaging of lesions in Kimura's disease has been noted to characterize it and differentiate it from other pathologies. We describe a case a recurrent Kimura's disease of the periparotid region and its MRI features with special emphasis on its characteristics on DWI and contrast enhanced sequences.
木村病是一种罕见的头颈部疾病，主要影响东方国家的成年男性。腮腺及腮腺周围皮下区域是头颈部最常见的发病部位。血常规检查显示外周嗜酸性粒细胞增多和血清IgE水平升高为其特征性表现，腮腺及腮腺周围区域无痛性肿胀可诊断为木村病。磁共振成像（MRI）一直是评估头颈部病变的重要手段。最近，人们对木村病病变的扩散加权成像（DWI）和对比增强MRI（CEMRI）成像产生了兴趣，以对其进行特征性描述并与其他病理情况相鉴别。我们描述了一例腮腺周围区域复发性木村病病例及其MRI特征，特别强调其在DWI和对比增强序列上的特点。
