Understanding Clivus Chordoma
Clivus chordoma is a rare tumor at the skull base’s base. It comes from notochord remnants. It’s usually not cancerous but hard to diagnose and treat because of where it is.
Introduction to Clivus Chordoma
Most adults get clivus chordomas, between 40 and 70 years old. They are a small part of skull base tumors but can greatly affect health. Clivus chordoma diagnosis often uses imaging because symptoms are not clear and come on slowly.
Pathophysiology of Clivus Chordoma
Clivus chordoma’s cause is complex, involving genes and environment. They start from notochord remnants from early development. Some genes might help them grow, but we’re still learning about this. These tumors spread and harm nearby nerves and blood vessels in the skull base.
| Aspect | Description |
|---|---|
| Origin | Notochordal remnants |
| Age Group Affected | 40-70 years |
| Symptoms | Headaches, vision problems, cranial nerve dysfunctions |
