Five cases of retroperitoneal lymphangioma are presented. In three patients the lesions were symptomatic, with resolution of the symptoms following resection. In two elderly patients the lesions were asymptomatic. Ultrasound demonstrated masses that ranged from 4 to 15 cm in maximal extent, and which were predominantly anechoic. Two contained septations and two echogenic debris. Computed tomography demonstrated the masses to be of water density, and allowed better delineation of the lesions to adjacent structures within the anterior pararenal space. Fine needle aspiration (FNA) produces a characteristic cytology of abundant lymphocytes, which may be intermingled with macrophages. It is considered that retroperitoneal lymphangioma has characteristic imaging features that allows a presumptive diagnosis, which can be confirmed by FNA.
本文报告5例腹膜后淋巴管瘤。3例患者的病变有症状，切除后症状缓解。2例老年患者的病变无症状。超声显示肿块最大径为4至15厘米，主要为无回声。2个含有分隔，2个有回声性碎屑。计算机断层扫描显示肿块为水样密度，能更好地显示病变与肾旁前间隙内相邻结构的关系。细针穿刺（FNA）产生具有丰富淋巴细胞的特征性细胞学表现，淋巴细胞可能与巨噬细胞混合。认为腹膜后淋巴管瘤具有特征性影像学表现，可作出初步诊断，FNA可确诊。
