摘　　要：目的探讨磁共振诊断脑干海绵状血管畸形(CM)的正确率及影像学特点。方法选取术前经磁共振诊断并经手术治疗的CM病例共67例。对照研究术后病理,对比各病理结果病例之间的磁共振表现特点。结果 67例病例中,60例病理为海绵状血管畸形,占89.6%;7例病理诊断为动静脉畸形(AVM)。21例(31.3%)术前磁共振上可见合并相邻的静脉发育异常。病理诊断海绵状血管畸形及AVM的两组病例,其磁共振影像学特点差异无显著性(P>0.05)。结论磁共振诊断CM有较高的正确率,但存在病理为AVM的可能性,CM易合并脑静脉发育异常,外科医生应该在手术中给予足够的重视。Objective To investigate the accuracy and imaging features of magnetic resonance imaging（ MRI） in the diagnosis of brainstem cavernous malformation. Method MRI features and postoperative pathological results of 67 pa-tients whose preoperative MRI met the diagnostic criteria of brainstem cavernous malformation were reviewed retro-spectively. Result After operation,60（89. 6%） patients＇ pathological results were cavernous malformation,7 pa-tients were diagnosed as arteriovenous malformation. 21（31. 3%） patients presented concomitant developmental ve-nous anomalies in the MRI. There was no statistical difference（P〉0. 05） between the MRI features of cavernous malformations and arteriovenous malformations. Conclusion Diagnosis of brainstem cavernous malformation by MRI has a high accuracy,but some patients with arteriovenous malformation may be diagnosed as cavernous malformation. Cavernous malformation is prone to coexisting with developmental venous anomaly. Neurosurgeons should know these during the surgeries.
