摘　　要：目的探讨磁共振成像（MRI）在颅脑外伤后眼上静脉扩张中的诊断价值。方法搜集经临床确诊为颅脑外伤的8例（8眼），对其眼眶MRI资料进行回顾性分析。结果8眼均有眼球突出（5眼是右眼突出，3眼是左眼突出），眼球后均可见迂曲扩张的眼上静脉，3眼的眼眶周可见静脉迂曲扩张，8眼均可见同侧海绵窦血管扩张。结论MRI可以清晰显示眼上静脉及眼眶内结构，并对眼上静脉扩张的病因具有鉴别诊断价值。Objective To investigate the magnetic resonance imaging（MRI） of the superior oph- thalmic vein expansion after traumatic brain injury. Methods Eight eyes of 8 cases were clinically diag- nosed as cerebral trauma from 2005 to 2010, and the orbital MRI were retrospectively analyzed. Results In the 8 patients, protruding eyeballs occurred in all of the 8 cases, in which 5 cases was in the right eye, 3 ca- ses was in the left eye. Superior ophthalimic vein expansion was observed in all cases. Periobital expansion of vein was observed in 3 cases. Homolateral sinus cavernosus vasodilatation occurred in each case. Conclu- sion MRI can clear display orbital structure and superior ophthalmic vein, and made differential diagnosis for expansion of superior ophthalmic vein.
