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).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"st2\">\n<jats:title>Case Description: <\/jats:title>\n<jats:p>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 \u201ccystic\u201d 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.
