Spinal neoplasia

ffelis

Introduction

  • Relatively uncommon disease.
  • Cause:
  • Signs: neurological deficits, hind limb paresis (depending on the localization along the spinal column).
  • Diagnosis: survey radiographs - myelography, cytological examination of cerebrospinal fluid, response to therapy.
  • Treatment: chemotherapy (for lymphoma); surgical decompression for osteosarcoma.
  • Prognosis: guarded.

Pathogenesis

Pathophysiology

  • Lymphoma arises from extramedullary hematopoeitic tissue in epidural fat   →   neoplastic cells accumulate in extradural space and may infiltrate meninges, vertebrae or muscles   →   pressure on spinal cord   →   clinical signs.
  • Rarely intradural lymphoma may occur.

Timecourse

  • Days to weeks.
  • Clinical signs usually develop acutely and progress rapidly.
