L6: Spinal Tumors Flashcards

1
Q

Spinal tumors are one of the challenging issues in neurosurgery why?

  • As they are present in a potentially narrow space containing neural tissue.

So they are mostly presented by neural deficits “Necessitating rapid, meticulous intervention to prevent further complications to the patient”
