Spontaneous spinal cord herniation is a rare cause of progressive myelopathy. Surgical repair can halt deficits and improve function, highlighting the need for early diagnosis.

Area of Science:

  • Neurosurgery
  • Neurology
  • Radiology

Background:

  • Spontaneous spinal cord herniation through a dural defect is an uncommon condition, potentially underdiagnosed before advanced imaging.
  • Progressive myelopathy necessitates consideration of rare etiologies beyond typical spinal cord compression.

Observation:

  • A 49-year-old male presented with progressive Brown-Sequard syndrome.
  • Magnetic resonance imaging (MRI) and CT myelogram revealed ventral spinal cord displacement at T6-T7 and posterior subarachnoid space expansion.

Findings:

  • Surgical exploration identified and reduced a spinal cord herniation through an anterior dural defect.
  • The dural defect was repaired using a lyophilized dura patch.
  • Post-operatively, the patient regained muscle power but sensory deficits persisted.

Implications:

  • Spontaneous spinal cord herniation should be considered in middle-aged patients with progressive myelopathy lacking typical compression signs.
  • Early diagnosis and surgical intervention are crucial for managing spinal cord herniation and potentially improving neurological outcomes.
