| 摘 要： | 目的分析眼部淋巴瘤的MRI表现,探讨MRI对该病的诊断价值。资料与方法对58例经手术病理证实的眼部淋巴瘤患者的MRI资料进行回顾性分析。结果 58例中,27例病变呈弥漫性分布,其中7例位于肌锥内,9例位于肌锥外,11例同时累及肌锥内外间隙;31例病变较局限,主要累及泪腺区24例,结膜3例,眼外肌2例,泪囊区1例,眼睑1例。31例局限性病灶边缘清晰,其中13例呈铸型生长;27例弥漫性病灶形态不规则,边缘模糊,与邻近结构分界不清。T1WI上46例呈中等或中等偏低信号,12例呈低信号;T2WI上39例呈中等信号,12例呈低信号,7例呈高信号;增强扫描后病灶均匀强化。结论眼部淋巴瘤在MRI上具有一定的信号特点,且MRI可清楚地显示病变范围及其与邻近结构的关系,对于该病的诊断具有重要意义。
