Idiopathic thoracic transdural intravertebral spinal cord herniation

Area of Science:

• Neurosurgery
• Neurology
• Radiology

Background:

• Idiopathic spinal cord herniation is a rare cause of thoracic myelopathy.
• It is frequently misdiagnosed due to inconsistent clinical and radiological findings, often mistaken for dorsal arachnoid cysts.

Observation:

• A 70-year-old man presented with idiopathic thoracic transdural intravertebral spinal cord herniation.
• This represents an extremely rare variant distinct from previously described ventral herniations.

Findings:

• The case underscores the diagnostic challenges posed by idiopathic spinal cord herniation.
• Intravertebral herniation is a distinct and exceptionally rare entity within this spectrum.

Implications:

• Accurate diagnosis is crucial for effective management of spinal cord herniation.
• Understanding the clinico-radiological features and pathophysiology aids in treating this rare condition.
