摘　　要：目的分析眶内海绵状血管瘤的MRI表现特征,提高对本病的诊断能力。方法回顾性分析11例眶内海绵状血管瘤患者的MRI平扫、脂肪抑制成像(SPIR)及增强扫描的表现特点。结果11例患者MRI扫描T1WI呈等信号8例,稍低信号3例,T2WI高信号11例,SPIR稍高信号11例。增强后动脉期中心轻度强化7例。MRI诊断8例为眶内海绵状血管瘤,3例为球后占位血管性肿瘤不除外。结论MRI对眶内海绵状血管瘤具有重要的诊断价值。Objective To analyse MRI features of orbital cavernous hemangioma（OCH） so that to improve the knowledge of this diseases. Methods The features of OCH at MRI plain scan,SPIR and enhanced scan in 11 cases were retrospectively analyzed. Results Of 11 cases,8 cases displayed iso -intensity and 3 were slight hypointensity on T1WI. 11 cases appeared as hyperintensity on T2WI and slight hyperintensity on SPIR. At arterial phase,7 cases were slight enhancement at the center of tumor. Based on MRI,8 cases were exactly diagnosed as OCH,the other 3 cases were considered as retrobulbarly angiogenic tumor. Conclusion MRI plays important role in diagnosis of OCH.
