Introduction to Spinal Cord Tumors
Spinal cord tumors are abnormal growths inside the spinal canal or spine bones. They are either primary spinal tumors or metastatic spinal tumors. Knowing the difference is key for right diagnosis and treatment.
Overview
These tumors can harm the spinal cord and its parts. Primary spinal tumors start in the spinal tissues. Examples are astrocytomas and ependymomas.
Metastatic spinal tumors come from other body parts and spread to the spine. They often start from cancers like breast, lung, or prostate.
Types of Spinal Cord Tumors
There are many types of spinal tumors, each unique:
- Astrocytomas: These come from astrocytes and are common in young adults.
- Ependymomas: These are from ependymal cells and are quite treatable.
- Nerve Sheath Tumors: These are usually harmless and come from nerve linings.
Symptoms and Signs
Spinal tumors show different symptoms based on their location and type. Common signs include:
- Pain: It can be sharp or spread along the nerve.
- Neurological Deficits: You might feel weak, numb, or lose sensation.
- Functional Impairments: You could lose motor skills or control over bowel/bladder.
Spotting these signs early is crucial for quick medical help and better treatment. MRI is key in finding these tumors because it shows clear images.
