Summary

Intervertebral disk extrusion is rare in cats. This case study details an acute intramedullary disk extrusion, identified by imaging, where disk material was found within the cat's spinal cord.

Area of Science:

  • Veterinary Neurology
  • Comparative Medicine
  • Spinal Cord Imaging

Background:

  • Intervertebral disk extrusion is uncommon in feline patients.
  • Intramedullary disk extrusion, where disc material enters the spinal cord parenchyma, is exceptionally rare in cats.

Observation:

  • A 5-year-old domestic shorthaired cat presented with acute neurological deficits.
  • Radiographic and magnetic resonance imaging (MRI) were performed to investigate the cause.
  • Imaging revealed mineralized disk material within the vertebral canal and spinal cord.

Findings:

  • The magnetic resonance imaging (MRI) confirmed the disk material was located intramedullary, within the spinal cord tissue.
  • A distinct linear trail of disk material extended from the intervertebral disk space into the spinal cord.

  • This linear trail may be a specific diagnostic indicator for intramedullary disk extrusion in cats.

    • Implications:

    • This case expands the understanding of spinal pathologies in cats.
    • Accurate diagnosis of intramedullary disk extrusion relies on advanced imaging techniques like MRI.
    • Recognizing imaging features like the disk trail can aid in diagnosing this rare condition.
