Spinal cysticercosis (NCC) is rare but serious, often requiring surgery for subarachnoid lesions. Intramedullary NCC may respond to steroids, with most patients achieving ambulatory recovery.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Cysticercosis is the most common parasitic infection of the central nervous system globally.
  • Neurocysticercosis (NCC) affects up to 4% of populations in endemic areas, predominantly intracranial.
  • Spinal NCC, accounting for 1.5-3% of cases, is a distinct entity with severe potential consequences due to the spinal canal's limited space.

Observation:

  • Spinal NCC lesions are typically located in the subarachnoid space (5/6 patients), causing spinal cord compression or CSF pathway obstruction.
  • One patient presented with an intramedullary spinal NCC lesion.
  • Mass effect from spinal NCC is poorly tolerated, leading to potential spinal cord compression and neurological deficits.

Findings:

  • Surgical excision was necessary for all patients with subarachnoid spinal NCC, especially when medical therapy failed (2/5 cases).

  • The patient with intramedullary spinal NCC improved with steroid therapy.
  • All treated patients showed variable improvement, ultimately becoming ambulatory.

    • Implications:

    • Prompt surgical intervention is crucial for severe or progressive spinal NCC deficits to prevent permanent injury.
    • Medical therapy may be suitable for stable, non-progressive spinal NCC cases.
    • Patient outcomes can be limited by pre-existing inflammatory spinal cord injury or arachnoidal adhesions.
