Choroid Plexus Tumors

What is Choroid Plexus Tumors?

Choroid plexus tumors are rare brain tumors that originate from the choroid plexus, a structure in the brain responsible for producing cerebrospinal fluid (CSF).

These tumors can occur at any age but are more commonly found in children. They are classified into different types based on their aggressiveness, with choroid plexus papillomas being non-cancerous (benign) and choroid plexus carcinomas being cancerous (malignant).

Side Effects of Choroid Plexus Tumors

The symptoms and side effects of choroid plexus tumors can vary depending on their size, location, and whether they are benign or malignant. Common symptoms may include headaches, nausea, vomiting (especially in the morning), changes in vision, and problems with balance or walking.

In some cases, these tumors can lead to increased pressure within the skull (intracranial pressure), which may cause further complications if not managed promptly.

How is Choroid Plexus Tumors Diagnosed?

Diagnosis of choroid plexus tumors typically involves a combination of imaging studies and a biopsy:

• Imaging Studies: MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans are commonly used to visualize the brain and detect any abnormalities, such as tumors.
  
• Biopsy: A biopsy involves taking a small sample of the tumor tissue for examination under a microscope. This helps in determining the type of tumor (benign or malignant) and guides further treatment decisions.

Potential Treatment of Choroid Plexus Tumors

Treatment options for choroid plexus tumors depend on several factors including the tumor type, size, location, and the patient's overall health. Treatment may include:

• Surgery: Surgical removal of the tumor is often the primary treatment for choroid plexus tumors, especially for choroid plexus papillomas. The goal is to remove as much of the tumor as possible without damaging surrounding brain tissue.
• Chemotherapy: For malignant choroid plexus tumors (carcinomas), chemotherapy may be recommended either before or after surgery to shrink the tumor and target any remaining cancer cells.
• Radiation Therapy: In some cases, radiation therapy may be used following surgery to destroy any remaining cancer cells and reduce the risk of tumor recurrence.
• Regular Monitoring: After treatment, regular follow-up appointments and imaging scans are necessary to monitor for any signs of tumor recurrence or new growth.
