BACKGROUND
Spinal aneurysms are rare causes of spontaneous subarachnoid hemorrhage.
METHODS
We present an unusual, initially occult, case of an upper thoracic intradural extramedullary isolated aneurysm arising from the T2 intercostal-radicular circulation that was initially angiographically occult but was discovered due to unique, albeit nonspecific, magnetic resonance imaging findings of spinal cord T2 hyperintensity and contrast enhancement that were noted to progress with a clinical picture of ictal rehemorrhage.
RESULTS
Repeat spinal angiography revealed a spinal aneurysm that was treated surgically.
CONCLUSION
In cases of sufficient clinical suspicion and nonspecific imaging findings, continued vigilance is advised in seeking an underlying pathoanatomic etiology.
背景
脊髓动脉瘤是自发性蛛网膜下腔出血的罕见病因。
方法
我们报告了一例不寻常的、最初隐匿的上胸段硬脊膜内髓外孤立性动脉瘤病例，该动脉瘤起源于T2肋间神经根循环，最初血管造影未显示，但由于脊髓T2高信号和对比增强等独特（尽管非特异性）的磁共振成像表现而被发现，且这些表现随着发作性再出血的临床表现而进展。
结果
重复脊髓血管造影显示了一个脊髓动脉瘤，并进行了手术治疗。
结论
在临床高度怀疑且有非特异性影像学表现的病例中，建议持续保持警惕以寻找潜在的病理解剖病因。
