目的探讨CT对囊性淋巴管瘤的诊断价值。
Objective To study ct value in diagnosing cystic lymphangioma.
目的探讨胎儿囊性淋巴管瘤的产前MRI特点及诊断价值。
Objective To observe the MRI characteristics and the value of prenatal diagnosis for fetal cystic lymphangioma.
结果4胎经MRI诊断为胎儿囊性淋巴管瘤，均由产后病理得到证实；
Results All 4 fetus were diagnosed as cystic lymphangioma with MRI, which was then proved pathologically.
结果：囊性淋巴管瘤的影像学特征为头颈部两侧或背侧的囊性包块，呈单囊或多囊表现，回声或信号可均匀或不均匀，病变范围可延伸至枕部或肩背部及纵隔。
Results:The cervical lymphangioma in fetus was characterized by a cystic mass, single or multilocular with septations, on the back or both sides of the neck, the echo and signal is uniform or not.
结果：儿童颈部淋巴管瘤的典型CT表现：肿瘤边缘光滑，呈密度均匀的囊性包块，增强扫描可见肿瘤囊壁较薄，呈轻度强化，囊内不强化。
Results: Typical CT findings of cl in children included: cystic mass with smooth margins, uniformed density, thin walls, minimal rim enhancement and lack of enhancement in cystic Spaces.
甲状舌管囊肿及鳃裂囊肿呈单房性，淋巴管瘤多为多房性，颈淋巴结囊性转移瘤伴有壁结节。
Most of the thyroglossal duct cyst and branchial cleft cyst were monolocular, while lymphangioma multilocular. Metastatic tumors of the cystic lymph nodes were always associated with wall nodule.
结论：淋巴管瘤有较为典型的影像学表现：囊性，薄壁肿块，密度较均匀，边界较清楚；
Conclusion:Lymphangioma are usually cystic, non-enhanced with thin wall, homogenous density and well-defined margin masses on imaging modalities.
