What Is Skull Base Chordoma?

Skull base chordoma is a rare type of bone cancer that primarily occurs at the base of the skull and along the spine. This tumor arises from remnants of the notochord, a structure present during embryonic development that eventually forms the spine. Although chordomas can develop in various locations, those that form at the skull base are particularly challenging due to their proximity to critical structures such as the brain, cranial nerves, and major blood vessels.

Chordomas are classified as low-grade malignant tumors, meaning they grow slowly but can be aggressive and difficult to treat. They account for approximately 1-4% of all primary bone tumors, making them quite uncommon. The average age of diagnosis is typically between 30 and 60 years, but they can occur at any age.

Types of Skull Base Chordoma

There are two main types of skull base chordomas:

• Classic Chordoma: This is the most common type, characterized by a gelatinous appearance and a tendency to invade surrounding tissues.
• Dedifferentiated Chordoma: This variant is more aggressive and has a higher likelihood of metastasis, making it more challenging to treat.

Causes and Risk Factors

The exact cause of skull base chordoma remains unclear, but certain factors may increase the risk of developing this tumor:

• Genetic Factors: Some individuals may have a genetic predisposition to chordomas, particularly those with conditions like familial chordoma syndrome.
• Age: Most cases are diagnosed in adults, particularly those aged 30 to 60.
• Gender: Males are more frequently affected than females.
