MRI revealed a large posterior extradural SAC extending from T2-T3 to T8, with associated spinal cord compression. Initial management involved T8 laminectomy and cyst fenestration under intraoperative neurophysiological monitoring, with partial clinical improvement. However, early recurrence with pseudomeningocele formation prompted a second surgery, including external CSF drainage. Persistent cerebrospinal fluid (CSF) leakage led to targeted epidural blood patching, followed by temporary stabilization.
