摘　　要：目的 探讨Kimura病的CT、MRI表现,提高该病的术前诊断水平.方法 回顾性分析11例经病理证实的Kimura病患者的临床特征、CT及MRI表现.11例Kimura病患者发生于（或累及）腮腺区7例,颌面部2例,硬腭1例,腹股沟1例（其中3例为异位复发,2例为原位复发）.均表现为无痛性肿物,平均病程2年以上;嗜酸性粒细胞均明显增高.结果 CT和MRI表现：5例单发结节,6例多发结节;最小者约6 mm×3 mm,最大者约60 mm ×34 mm;较大结节边界不清楚,较小者边界清楚,邻近脂肪间隙内见条索影浸润,10例颌面部病灶均位于浅筋膜下;CT显示9例密度均匀,稍低于肌肉密度;3例在MR T2WI上呈稍高信号,在T1 WI上呈等或稍低信号;11例肿块呈中度至重度、均匀或不均匀强化;9例肿块（8例颌面部、1例腹股沟）伴有同侧（或双侧）引流区淋巴结肿大,边界清楚,无坏死,无融合,强化明显.结论 Kimura病具有一定的临床和影像特征,结合实验室检查,可以进行正确诊断.Objective To study the imaging features of Kimura disease to improve diagnostic ability prior to surgery.Methods The clinical manifestations and CT and MR findings of 11 patients with histologically confirmed Kimura disease were retrospectively analyzed.All 11 tumors originated from （or involved）the parotid region in 7 cases, the maxillofacial region in 2 cases, the palate in one case and the groin in one case.Clinically, the lesions showed asymptomatic tumors with the mean clinical course over 2 years.The increase of cosinophilic granulocyte was found in all 11 cases.Results On CT and MRI,5 patients were single masses and others were muhi-nodular masses.The smallest lesion was 6 mm×3 mm,and the largest lesion was 60 mm × 34 mm.The lesions were almost ill-defined in the subcutaneous tissue,especially 10 locating underlying superficialfascia in head and neck.On CT,the lesions showed homogeneous hypodense to the muscle in 9 patients.The lesions appeared isointeuse signal or slightly hypointense on MR T1WI and slightly hyperinteuse on T2WI in 3 patients.All lesions revealed moderate or marked, and homogeneous or inhomngeneous enhancement.Regional lymph nodes （eight cases in the maxillofacial region and one in the groin） enlarged without necrosis and fusion, and with marked enhancement.Conclusion The clinical and imaging findings of Kimura disease have some characteristics, the diagnosis can be made combined with the laboratory examination.
