摘要
目的分析婴幼儿四肢海绵状淋巴管瘤的MRI表现,以提高对该病的认识。方法对13例经手术病理证实的、年龄20 d～3岁2个月的四肢海绵状淋巴管瘤患儿MRI图像进行回顾性研究,分析病灶的部位、形态、边缘、信号特征以及增强表现等。结果除1例合并感染误诊为血管淋巴管瘤外,其余12例均明确诊断为海绵状淋巴管瘤,MRI表现为皮下软组织增厚,弥漫分布多个迂曲"蚯蚓状"或囊状扩张淋巴管,呈均匀长T1、长T2信号,边界清楚,2例增强扫描显示扩张的淋巴管无强化。结论 MRI可清晰显示肿瘤的部位、形态、大小及与周围结构的关系,对海绵状淋巴管瘤手术治疗和监测复发有重要价值。
Objective To analyze the MRI and pathological appearance of limb cavernous lymphangioma in children,in order to improve awareness of the disease.Methods 13 patients with histologically confirmed cavernous lymphangioma were collected and retrospectively analyzed.The age ranged from 20 days to 3.2 years.The site,shape,margin,signal intensity and enhancement of the lesions were evaluated.Results One patient complicated with infection was misdiagnosed as hemolymphangioma,and the other 12 patients showed thickened subcutaneous tissue and multiple dilated lymphatic channels shaped like earthworms or cysts.These lymphatic channels had homogeneous long T1,long T2 signals with clear margins.Contrast enhancement MRI was conducted in 2 patients.These dilated lymphatic channels were not enhancement.Conclusion MR imaging can exactly evaluate the location,the shape,the size and the relation with peripheral structures of the tumor and help in planning surgery or monitoring palindromia.
