摘　　要：目的 :分析头颈部嗜酸性淋巴肉芽肿(ELG)的CT表现,以提高对该病的诊断准确性。方法 :回顾性分析11例经病理证实的头颈部ELG的CT表现及相关临床资料。结果:发生在颌下区5例,腮腺5例,耳后皮下1例;双侧发病2例,单侧发病9例。其中颌下区病变最大者截面3.6 cm×2.5 cm,腮腺病变最大者截面9.0 cm×5.0 cm,耳后病变较大者1.5 cm×0.8 cm。CT表现为颌下区病变(累及腺体或淋巴结)体积明显增大,增强扫描后病变以均匀或不均匀强化为主。腮腺病变表现为腮腺体积增大,密度不均匀,内示多发结节或团块影,增强扫描呈结节样强化。1例发病在左侧耳后皮下,表现为左耳后皮下2枚结节影。体积增大的病灶均对周围组织产生不同程度的压迫或浸润。外周嗜酸性粒细胞均增加。结论:头颈部ELG的影像表现有一定特征性,仔细分析其特征并结合临床表现、实验室检查指标,术前作出诊断并不困难。Objective：To analyze CT imaging characteristics of eosinophilic lymphoid granuloma of head and neck to improve its diagnostic accuracy. Methods：We retrospectively reviewed the CT imaging of 11 cases of eosinophilic lymphoid granuloma of head and neck confirmed immunohistochemically. Relevant clinical data was also obtained. Results：Of 11 cases,eosinophilic lymphoid granuloma were located in the submandibular region（n=5）,parotid gland（n=5） and retroauricular region（n=1） in 2bilateral cases and 9 unilateral cases. The maximum size was 3.6 cm × 2.5 cm in submandibular region,9.0 cm × 5.0 cm in parotid gland,and 1.5 cm × 0.8 cm in retroauricular region. The lesions in submandibular region showed enlarged masses,and were homogeneous or heterogeneous after enhancement. The diseased parotid glands were enlarged and heterogeneous with nodular enhancement. One retroauricular lesion demonstrated subcutaneous nodules. All the enlarged lesions compressed or infiltrated the adjacent tissue in varying degrees. Peripheral eosinophils increased in all cases. Conclusion：Specific imaging manifestations of Kimura＇s disease are available. With serious observation and close connection with clinic and laboratory examination,the correct diagnosis is not difficult to be made before operation.
