目的：探讨成人胃肠道囊性淋巴管瘤的CT表现及其诊断价值。方法回顾性分析经病理证实的5例成人胃肠道囊性淋巴管瘤患者的CT表现，并与手术和病理结果进行对照。结果5例患者中，3例单发、2例多发；发生于胃壁1例，十二指肠1例，回肠1例，回肠伴肠系膜多发病灶1例，回肠、结肠伴腹膜后多发病灶1例；病灶大小为2.4~23.7 cm；其中4例病灶呈匍行生长趋势，伸入组织间隙；5例病灶均呈水样低密度囊性病灶，边界清晰，增强后均未见强化。结论胃肠道囊性淋巴管瘤多为单房囊腔，呈匍行生长，内含均匀液性低密度影，囊壁边界清楚，囊壁及其内容物一般无强化，与其囊性病理学特征相符。

Objective To study the imaging findings and diagnostic value of CT in cystic gastrointestinal tract lymphangiomas.Methods CT findings of 5 adult patients with pathologically confirmed cystic gastrointestinal tract lymphangiomas were collected and retrospectively reviewed. These findings were compared with operative and pathological results.Results The size of lesions in 5 cases was 2.4-23.7 cm. The lesions were solitary in 3 cases (60%) and multiple in 2 cases including gastric wall, duodenal wall, ileum wall and colon wall, etc. 4 cases showed creeping growth trend, extending into the interstitial space. CT showed non-enhancing cystic masses with homogeneous low-attenuation as water, smoothly marginated and thin-walled. Conclusion Most of cystic gastrointestinal tract lymphangiomas are solitary cystic masses with creeping growth trend. The main CT manifestations are non-enhancing cystic masses with homogeneous low-attenuation, smoothly marginated and thin-walled. The findings are in accordance with the pathological characteristics.
