| 摘要 目的：探讨头颈部木村病的CT、MRI的影像学表现。方法：对6例经手术或活检病理证实的头颈部木村病的CT及MRI影像学表现进行回顾性分析。结果：本组6例以中青年男性患者多见，病灶位于耳周2例、颊面部1例、颌下区1例，腮腺区1例、头皮下1例，均表现为无痛性肿块。3例CT表现为单侧或双侧、单发或多发等或略高密度软组织肿块，密度均或不均，边缘清楚或局部欠清，伴邻近皮下组织受累；增强扫描病灶表现为不同程度强化。3例MRI表现为对比邻近肌肉信号，病灶在T1WI 上为等、稍高信号，在T2WI上为高信号，大部分病灶中等至明显强化。本组6例病变均伴有周围多发淋巴结肿大及实验室检查外周血嗜酸性粒细胞增多，可伴病侧局部皮下脂肪层萎缩。结论：头颈部木村病的CT、MRI影像表现有一定特征性，结合临床病史及实验室检查，可提高木村病的诊断准确率。 |

| ABSTRACT Objective: To study the CT and MRI findings of Kimura's disease in head and neck. Methods: The CT and MRI findings of 6 cases of Kimura's disease in head and neck confirmed by surgery or biopsy were retrospectively analyzed. Results: In the group of 6 cases, they were more common in young and middle-aged male patients. These lesions were located around ear in 2 cases, in cheek in 1 case, in submandibular area in 1 case, in parotid gland area in 1 case, and under scalp in 1 case; and all of them showed painless mass. The CT findings of 3 cases showed unilateral or bilateral, single or multiple soft tissue mass with moderate or slightly high density (homogeneous or heterogeneous) and clear margin (or local unclear margin), getting adjacent subcutaneous tissue involved; lesions showed varying degrees of enhancement after contrast media administration. The MRI findings of 3 cases showed the lesions were manifested as moderate or slightly high signal on T1WI, and high signal on T2WI in contrast to signal of adjacent muscle; moderate to avid enhancement was found in most lesions. All lesions in this study group were accompanied by multiple peripheral lymph nodes enlargement and laboratory examination of positive findings of peripheral blood eosinophils increasing; the local subcutaneous fat layer atrophy might be found in the affected side. Conclusion: The CT and MRI findings of Kimura's disease in head and neck have certain characteristics. Combined with clinical history and laboratory examination, the diagnostic accuracy of Kimura's disease can be improved. |
