摘　　要：目的:探讨淋巴管瘤的CT、MRI影像表现特征。方法:回顾性分析20例经手术病理证实的淋巴管瘤的病例资料,CT检查者14例,MRI检查者9例,总结其CT及MRI表现特点。结果:根据淋巴管瘤的发生部位将其分为两组,即非实质性脏器组16例,实质性脏器组4例。典型CT、MRI表现为单囊或多囊分隔状薄壁囊性病变,形态各异,爬行或塑型生长,少钙化,但位于肾上腺的淋巴管瘤囊壁及分隔可见钙化。CT对于病变的钙化显示优于MRI,而MRI对病变的囊性特征、病变内成分的判断优于CT,并能完整显示囊壁及分隔。结论:淋巴管瘤的CT、MRI表现具有一定的特征性,CT及MRI的影像表现有互补,二者联合应用对其定位及定性诊断有重要价值。Objective： To investigate the CT and MR imaging features of lymphangioma.Methods： Retrospective analysis on the CT and MRI features was performed in 20 cases with lymphangioma confirmed by operation and post-operative pathology. In the 20 cases,14 received CT scans（ 4 were plain scans and 10,plain plus enhanced scans）,and 9 were given MRI examination（ plain scans in 7 and plain plus enhanced scans in 2）.Results： The cases were divided into two groups by the location of lymphangioma. Sixteen cases were involvement of non-parenchymal organs（ cervical fascia space in 9,retroperitoneal in 3,axillary in 2,abdominal cavity in 1 and back skin in 1）,and 4 of parenchymal organs（ adrenal gland in 2,spleen in 1 and kidney in 1）.Lymphagnioma was characterized on CT and MRI by large,thin-walled,single or multiseptate cystic masses,with diverse shape,creeping or plastic model growth. Calcification was rarely seen in this type,yet was observed in lesions involved in adrenal gland at the cystic wall and the separation（ 2 cases）. CT was more competent in revealing calcification at the lesion than MRI,whereas MRI was superior to CT in exposing the cystic features and composition of the lesion,and better to exhibit full capsule wall and the separation.Conclusion： Lymphangioma has its specific presentation on either CT or MRI,suggesting that combined use of the two techniques can result in more accurate diagnosis of this condition.
