摘　　要：目的:探讨成人腹部囊性淋巴管瘤的CT表现及其诊断价值。材料和方法:回顾性分析6例经病理证实的腹部囊性淋巴管瘤的CT表现。结果:3例起源于小肠系膜,1例起源于结肠系膜,2例发生在腹膜后腔。6例均为多房型。2例呈巨大长袋状,2例形态不规则,2例为分叶状囊肿。囊壁菲薄,光滑,囊内密度均匀,部分囊壁和间隔可见增强。2例可见"血管穿行征",2例沿组织间隙蔓延呈"爬行性生长"改变。结论:肠系膜及腹膜后囊性淋巴管瘤是腹部的少见囊性病变,CT能够准确地显示病变的形态学特征和部位,并能够提供相应的诊断依据,帮助与其他囊性疾病鉴别。Purpose： To discuss the CT findings of abdominal cystic lymphagioma in adult, and to evaluate CT diagnostic value. Materials and Methods： The CT findings of six cases with abdominal cystic lymphagioma by pathology were analyzed retrospectively. Results： Three cases were originated from mesenterium, and one from mesocolon, two cases located in retroperitoneum. There were muhiloculated cysts in all cases. Two lesions to offer giant long-sack shape, two lesions were irregulari shape and two were lobulated. The cystic wall was thin and smooth, the cystic density was homogeneous, the walls and septa of the cysts were partially enhanced. Two cases had vessel traverse sign. Two lesions extended along the blank of organs as creeping. Conclusion： Cystic lymphangioma of mesenteium and retropefitoneum is a rare cystic disorder, CT scanning can precisely display the morphologic characteristics and the location of lesions, provide diagnostic evidences and help to differentiate it from other cystic diseases.
