Oligodendroglioma

Oligodendroglioma is a rare brain tumor that begins in glial cells called oligodendrocytes. These tumors are usually slow-growing but can spread into nearby brain tissue, which can make complete removal difficult. They rarely spread outside the brain or spinal cord. 

Types & Stages 

Oligodendrogliomas are grouped by grade:

• Grade II (low-grade): Slow-growing and often present for years before causing symptoms. They usually respond well to treatment.
   
• Grade III (anaplastic/high-grade): Faster-growing, more aggressive malignant tumors that are harder to treat.
   

Signs & Symptoms

Common symptoms may include: 

• Seizures
• Balance problems
• Memory problems
• Changes in behavior
• Trouble speaking
• Difficulty thinking clearly
• Numbness on one side of the body

Diagnosis  

Diagnosis may involve:

• Neurological exam
• MRI or other imaging tests
• Biopsy to confirm the tumor type

Treatment

Treatment options may include:

• Surgery to remove as much of the tumor as possible
• Radiation therapy
• Chemotherapy

Risk Factors

Possible risk factors include:

• Age (most common in adults in their 40s and 50s)
• Prior radiation exposure to the head or neck
• Race (most common in white people who do not have Hispanic ancestry)

Screening

There is no routine screening for oligodendroglioma. Diagnosis depends on symptoms and medical evaluation.
