腹部囊性淋巴管瘤的CT诊断

CT Diagnosis of Abdominal Cystic Lymphangioma

目的:探讨腹部囊性淋巴管瘤的CT表现及其诊断价值。材料与方法:回顾性分析8例经病理证实的腹部囊性淋巴管瘤的CT资料,结合文献对病变的影像表现进行分析。结果:4例起源于小肠系膜,1例起源于结肠系膜,1例起源于脾脏,2例发生在腹膜后腔。5例为多房性,3例为单房。4例较大,形态欠规则,且沿组织间隙呈"爬行性生长",其中1例可见"血管穿行征";4例呈类圆形。囊壁菲薄,囊内密度均匀,部分囊壁和间隔可见增强。结论:CT可准确的显示病变的形态学特征和部位,并能提供相应的诊断依据,帮助与其他囊性病变鉴别。

Purpose：To discuss the CT findings of abdominal cystic lymphagioma.and to evaluate CT diagnostic value.Materials and Methods：CT imaging features of abdominal cystic lymphangioma in 8 cases proved by pathological diagnosis were retrospectively analysed with the literature review.Results：Four cases were originated from mesenterium,and one from mesocolon,one case originated in the spleen,two cases located in retroperitoneum.Five cases were multiloculared cysts,three cases of unilocular cyst.Four lesions were giant and irregular shape,and the lesions extended along the blank of organs as creeping,one case had vessel traverse sign;four lesions were similar cycle.The cystic wall was thin and smooth,the cystic density was homogeneous,the wall and septa of the cysts were partislly enhanced.Conclusion：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.
