A case of cervical intrathecal extramedullary cavernous angioma is presented. The rarity of this lesion in comparison with the more frequent vertebral cavernous angiomas with secondary extension to the epidural space is emphasized. The special features of this case are noted: the acute clinical onset due to recurrent subarachnoid hemorrhages, the visualization only by means of magnetic resonance imaging, and the unusual cervical level. The most debated characteristics of these lesions and the relevant literature are summarized.
本文报告一例颈段鞘内髓外海绵状血管瘤。强调了该病变与更常见的椎体海绵状血管瘤继发硬膜外扩展相比的罕见性。记录了该病例的特殊特征：因反复蛛网膜下腔出血导致急性临床起病，仅通过磁共振成像才能显示，以及不寻常的颈椎节段。总结了这些病变最具争议的特征及相关文献。
