目的探讨超声诊断胎儿先天性淋巴管囊肿的临床意义。方法回顾分析2005年7月～2009年4月12例胎儿先天性颈部淋巴管囊肿超声特点。结果所有病例均在13～28周行超声检查时发现,均为分隔水囊瘤,其中伴多发畸形2例,伴胸腹水3例(皮肤水肿2例,心包积液1例),胎死宫内2例,其声像特点表现为胎儿头颈部周围呈“茧状物”包绕,囊性肿块或在躯体、四肢肢体周围形成弥漫性囊性暗区,内均见分隔呈“网状”或“车轮状”。结论超声检查是诊断胎儿先天性颈部淋巴管囊肿的直接有效的首选方法,且与胎儿染色体异常关系密切。
Objective To investigate the clinical significance of ultrasonic diagnosis of congenital lymphatic cyst in fetus. Methods From July 2005 to April 2009, 12 cases of congenital cervical lymphatic cyst were retrospectively analyzed. Results All patients underwent ultrasound examination at 13 ~ 28 weeks. All of them were isolated cystic neoplasms, including 2 cases with multiple deformities, 3 cases with ascites and pleural effusion (skin edema in 2 cases, pericardial effusion in 1 case), fetal death In 2 cases, the sonographic features of the fetus around the head and neck were “cocoon ” wrapping, cystic mass or in the body, limbs around the formation of diffuse cystic dark area, were separated within the “Mesh” or “Wheels”. Conclusion Ultrasonography is the direct and effective method for diagnosing congenital lymphatic cysts in the neck of the fetus, and it is closely related to fetal chromosomal abnormalities.
