儿童体表淋巴管瘤的磁共振影像诊断

目的探讨儿童体表淋巴管瘤的磁共振影像学表现,评价磁共振影像诊断在儿童体表淋巴管瘤的价值,提高对淋巴管瘤的影像诊断水平。方法回顾性分析2014年1月～2018年12月年经手术或穿刺病理证实的的儿童体表淋巴管瘤42例的磁共振影像。结果单纯囊性淋巴管瘤26例,海绵状淋巴管瘤9例,血管淋巴管瘤7例。40例均表现为多房囊性结构,2例表现为单囊结构;18例病例可见液液平面;7例见血管穿行征;4例可见血管挤压征;20例表现为混杂信号,22例表现为长T1长T2信号;颈部及腋下大部分淋巴管瘤呈侵袭性生长,四肢及头皮肿物呈爬行性生长。结论儿童体表淋巴管瘤磁共振影像具有一定的特征,磁共振对儿童淋巴管瘤的诊断有重要的价值,能准确判断病灶的范围,对临床手术评估及内科治疗具有重要的意义。

Magnetic resonance imaging diagnosis of body surface lymphangioma in children

Objective To investigate the magnetic resonance imaging findings of the body surface lymphangioma in children,evaluate the value of magnetic resonance imaging diagnosis in children with body surface lymphangioma and improve the imaging diagnosis level for lymphangioma.Methods The magnetic resonance imaging findings of 42 children with surface lymphangioma confirmed by surgery or puncture pathology from January 2014 to February 2018 were analyzed retrospectively.Results There were 26 cases of cystic lymphangioma,9 cases of cavernous lymphangioma and 7 cases of vascular lymphangioma.Multiocular cystic structure was found in 40 cases and single cystic structure was found in 2 cases.Liquid-liquid plane was seen in 18 cases,vascular permeation sign in 7 cases,and vascular compression sign in 4 cases.Mixed signal was detected in 20 cases and long T1 and long T2 signal was detected in 22 cases.Growth of most lymphangioma was invasive in the neck and axilla and crawling growth of masses was observed in the extremities and scalp.Conclusion Magnetic resonance imaging of the body surface lymphangioma in children has certain characteristics.Magnetic resonance imaging is of great value in the diagnosis of lymphangioma in children,which can accurately determine the extent of lesions and is of great significance for the clinical surgical evaluation and medical treatment.
