摘　　要：目的:探讨儿童颈肩部淋巴管瘤的MRI影像表现,以加深对该疾病的认识。方法:26例经手术病理证实的淋巴管瘤MRI数据纳入回顾性研究,分析病灶的部位、结构形态与边缘、信号特征以及增强表现等。结果:病灶全部位于组织间隙内,其中80.8%位于肌间隙内,其余位于皮下间隙。病变由多个囊性结构构成,可以分为单囊为主型(55%)和多囊型(45%),25例病灶内有分割,88.5%的病灶形态不规则。87%的病灶T1WI呈等低信号且不均匀,全部病灶在T2WI呈高信号,多囊者各囊内信号可不同。增强后半数有分隔强化。结论:儿童颈肩部淋巴管瘤典型MRI表现是位于组织间隙内的、不规则的多囊性病灶,呈长T1长T2信号,常有分隔,分隔可强化或不强化,不同的囊内信号可不同。Purpose：To evaluate the MR features of child＇s lymphangioma in the neck and shoulder in order to emphasize the recognition.Methods：Twenty-six patients with histologically confirmed lymphangioma in the neck and shoulder were enrolled in our retrospective study. The site,structure,shape,margin,signal intensity and enhancement of the lesions were evaluated.Results：All the lesions were located in the tissue spaces and 80.8% of the lesions grew alongside the space between the muscles and others subcutaneously. The lesion were multicystic and could be classified into mono-cystic predominant type （55%） and multi-cystic predominant type （45%）. The septum was seen in 25 patients and the irregular shape was seen in 88.5% of them.The lesions were iso-or hypo-intensity on T1WI （87%） and hyper-intensity on T2WI （100%）. The different cysts in the same lesion would have different signals. The septum enhancement was seen in half patients.Conclusion：The typical MR finding of lymphangioma of neck and shoulder in children was the irregular multicystic lesion which grew between the muscles or subcutaneously. The cysts had long T1,long T2 signal,and might have different intensity in the same lesion. The septum was commonly seen and could be enhanced.
