| 目的 探讨眼眶淋巴管瘤的MRI表现与诊断价值。方法 对经手术病理证实的眶内淋巴管瘤患者23例行MRI常规扫描与压脂增强扫描,分析其MRI表现特征。结果 根据MRI表现,淋巴管瘤可分为3型:①单囊型:瘤体呈单发囊性肿块,长T1、长T2信号,部分信号不均匀,水成像显示呈囊状高信号;②多囊型:瘤体呈多个大小不等囊状灶,生长范围广泛,体积较大,部分囊腔内出血而形成巧克力囊肿,信号不均匀;③特殊部位型:瘤体发生于结膜或眼球前方,肿块呈扁平状分布,略长T2信号,境界较清,增强后轻度强化。结论 采用正确的MRI扫描方法,能明确显示淋巴管瘤的形态、范围与信号改变,结合三维重建图像,能为临床手术提供明确的定位与定性信息。 |

| Objective To probe the value and representation of MRI in diagnosis of orbital lymphangioma. Methods Twenty-three cases of lymphangioma confirmed by operation pathology, were scanned with common and post-contrast MRI, and their special findings were analyzed. Results Lymphangioma was divided into three types by the appearance of MRI: ①Single cyst, the body of tumor was single cyst and long T1 long T2, part of it was uniform. MR hydrography show it was cystiform with high signal. ②Multicystic type, the tumor was multilocular cystic,with diffuse growth,large volume. Part of cystic cavity was chocolate cyst with hemorrhage. ③Special position, the tumor took place in conjunctiva or in the front part of eyeball,and tabular distributing with long T2 signal,legible edge,a little enhancement on post-contrast image. Conclusion MRI can display the modality,range and changes of signal of lymphangioma,and it can provide explicit localization and qualitative information for clinical operation. |
