Title: Serial magnetic resonance imaging findings in subarachnoid hemorrhage due to an initially angiographically occult type II spinal aneurysm: Case report. Cord-id: bxifock7 Document date: 2017_1_1
ID: bxifock7
Snippet: 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
Document: 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.
