Spontaneous intralesional hemorrhages are extremely rare and are typically found within intracranial arachnoid cysts. Here, a 55-year-old female presented with a spontaneous hemorrhage into a cervical spine arachnoid cyst warranting surgical intervention (i.e., fenestration/excision/occlusion). Case Description: A 55-year-old female presented with 3 weeks of dull pain in the cervicothoracic region. She subsequently developed paresthesias and progressive lower extremity weakness with (urinary incontinence. The cervical magnetic resonance revealed a right anterolateral intradural extramedullary “cystic” lesion extending from C7 to T2; it contained a heterogeneous signalon T2W sequences, and a fluid-fluid level was documented on the T2-GRE and FLAIR sequences. At surgery, consisting of a laminectomy, two hemorrhagic cystic lesions were identified and removed. Histological findings were consistent with hemorrhagic into an arachnoid cyst. Conclusion: Only rarely hemorrhages develop in intraspinal intradural extramedullary spinal arachnoid cysts.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/0e6b6fab-20cd-4c2f-9cb6-c7de591f8023/featured/hero-cropped-1781560928808.jpg","publishDate":"2022-09-23T00:00:00.000Z","doi":"10.25259/SNI_343_2022","categories":["Spine","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2022/09/11891/SNI-13-427.pdf"}
