目的 探讨木村病的CT、MRI表 现。方法 对13例经手术切除并病理证实 的木村病的影像征象进行回顾性分析。 结果 患者临床体征均为一侧或两侧颌面 部、上肢、腋窝、腹股沟无痛性肿块，及 局部淋巴结肿大，并伴随外周血嗜酸性粒 细胞明显升高。5例病灶分别位于腮腺、 下颌区、颈部、腹股沟区及腋窝，表现为 边界清晰的结节状影，增强扫描明显均匀 强化；8例病灶分别位于腮腺、泪腺、耳 周、下颌区、上肢，表现为边界模糊的斑 块状影，增强扫描大多强化不均匀。结论 木村病的CT、MRI表现有其特征性，结合 病史及实验室检查，有助于木村病与其他 病变的鉴别。

Objective To study the CT and MRI findings of Kimura's disease (KD) in order to improve diagnosis of it. Methods The imaging finding of 13 patients with histologically confirmed KD were analyzed retrospectively. Results 13 patients had common clinical features with painless mass and local lymphadenectasis, lesions occured in maxillofacial region, upper limb, axilla, inguina respectively. All patients accompanying peripheral blood eosinophilia were also observed. Five patients showed soft tissue nodules with welldefined margins and homogeneous enhancement in parotid gland, submandibular region, neck region, axilla, inguina respectively. Eight patients showed soft tissue swelling with ill-defined margins and heterogeneous enhancement in parotid gland, lacrimal gland, periauricular region, submandibular region, upper limb respectively. Conclusion The CT and MRI findings of KD have some characteristic features. Combining with the clinical manifestations and laboratory examinations, the diagnosis could be made.
