Description
Neuro-oncology spine disorders involve the diagnosis and treatment of tumors affecting the spinal cord, spinal column (vertebrae), and surrounding membranes (meninges). These conditions can be primary (originating in the spine) or, more commonly, metastatic (spreading from other cancers like breast, lung, or prostate). They are considered a distinct, complex, and often “orphan” field of neuro-oncology that requires a multidisciplinary team to manage pain, neurological deficits, and mechanical instability.

Key Aspects of Neuro-Oncology Spine Disorders:
1. Types of Spinal Tumors
Spinal tumors are classified by their location relative to the spinal cord:

Extradural (90-95% of cases): Located outside the dural sac, often involving the vertebral bone, and are typically metastatic.
Intradural-Extramedullary (5-10% of cases): Located inside the dura but outside the spinal cord. Most are benign, such as meningiomas (usually in the thoracic spine) or nerve sheath tumors (schwannomas, neurofibromas).
Intramedullary (Rare): Arise within the spinal cord itself, primarily ependymomas (most common) or astrocytomas.
