Childhood Ependymoma: A Rare Type of Brain Tumor

Childhood ependymoma is a rare type of tumor that forms in the brain or spinal cord of children. It starts in cells that line the ventricles, which are fluid-filled areas of the brain and spinal cord.

• Age of Diagnosis: The average age of diagnosis for childhood ependymoma is around 5 years old.
• Symptoms: Symptoms can include tilted head, loss of balance, difficulty walking, and other neurological problems [9].
• Incidence: Childhood ependymoma accounts for approximately 9% of all childhood brain tumors, with about 200 cases diagnosed in the United States each year [11].

Causes and Characteristics

The cause of ependymoma is unknown. Ependymal cells make cerebrospinal fluid (CSF), which circulates through the ventricles and spinal cord. Childhood ependymoma is distinct from adult tumors, with different molecular and clinical features [3].

• Grades: Primary CNS tumors are graded based on a tumor tissue analysis performed by a neuropathologist. Ependymomas can be classified into three grades: grade 1 (myxopapillary), grade 2 (classic), and grade 3 (anaplastic) [15].
• Location: Childhood ependymoma typically forms in the brain or spinal cord, with some cases occurring near the base of the brain.

Common Signs and Symptoms of Childhood Ependymoma

Childhood ependymoma, a type of brain tumor, can manifest in various ways, affecting the child's overall health and well-being. The symptoms can be subtle at first but may worsen over time if left untreated.

• Headaches: A frequent and recurring headache is one of the most common symptoms of childhood ependymoma [1][2].
• Nausea and Vomiting: Many children experience nausea and vomiting, which can be severe in some cases [3][4].
• Weakness or Fatigue: As the tumor grows, it can cause weakness or fatigue in the child's body [5].
• Vision Problems: Some children may experience vision problems, such as blurred vision or double vision [6][7].
• Balance and Coordination Issues: Ependymoma can affect the child's balance and coordination, leading to difficulties with walking or maintaining posture [8][9].
• Mood Changes: Children with ependymoma may exhibit mood changes, irritability, or crankiness due to the tumor's impact on their brain function [4][10].

It is essential for parents or caregivers to be aware of these symptoms and seek medical attention if they suspect that their child might have a brain tumor. Early detection and treatment can significantly improve the chances of successful recovery.

Diagnostic Tests for Childhood Ependymoma

Childhood ependymoma, a type of brain and spinal cord tumor, requires accurate diagnosis to determine the best course of treatment. The following diagnostic tests are commonly used to diagnose childhood ependymoma:

• Imaging Studies: Advanced imaging studies such as MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans are often used to visualize the brain or spinal cord and detect any abnormalities.
  • MRI is a non-invasive test that uses magnetic fields and radio waves to produce detailed images of the brain or spinal cord. It may be used along with specialized imaging techniques such as magnetic resonance angiography [6].
  • CT scan or MRI with or without contrast can help doctors see tumors, growths, or abnormalities in the brain or spinal cord [9].
• Biopsy: A biopsy involves removing a small sample of tissue from the tumor for examination under a microscope. This is often done during surgery to confirm the diagnosis and determine the type of ependymoma.
  • A neuropathologist should review the tumor tissue to get an accurate diagnosis [10].
• Spinal Tap (Lumbar Puncture): A spinal tap may be performed to determine whether the tumor has spread to the spine and/or spinal fluid.
  • This test involves inserting a needle into the lower back to collect cerebrospinal fluid for examination [8].

Other Diagnostic Tests

In addition to these tests, other diagnostic procedures such as CT angiography (CTA) may be used to help plan surgery.

• CT Angiography (CTA): CTA is a test that uses contrast material and CT scans to create detailed images of the blood vessels in the brain. This can help doctors plan surgery [3].

Importance of Accurate Diagnosis

Accurate diagnosis is crucial for determining the best course of treatment for childhood ependymoma. The type and location of the tumor, as well as whether it has spread, will influence the treatment plan.

• Molecular Testing: Since there are different types of ependymomas, molecular testing may be necessary to determine the accurate diagnosis [2].

Treatment Options for Childhood Ependymoma

Childhood ependymoma, a type of brain and spinal cord cancer, can be treated with various drug therapies. The treatment approach may vary depending on the age of the child, the location and size of the tumor, and other factors.

• Chemotherapy: Chemotherapy is a common treatment for childhood ependymoma. It uses drugs to kill or slow down the growth of cancer cells. Chemotherapy may be given alone or in combination with other treatments, such as radiation therapy.
• Targeted Therapy: Targeted therapy is a type of treatment that uses drugs or substances to identify and attack specific cancer cells. This approach can help reduce side effects and improve treatment outcomes.
• Valproic Acid: Valproic acid is a drug that has been added to standard chemotherapy regimens for childhood ependymoma. It may help improve treatment outcomes in patients who cannot receive radiation therapy.

Treatment Regimens

Several treatment regimens have been studied in children with ependymoma:

• Cisplatin, Cyclophosphamide, Etoposide, and Vincristine: This combination of chemotherapy drugs has shown promising results in infants with ependymoma.
• Valproic Acid and Chemotherapy: Adding valproic acid to standard chemotherapy regimens may improve treatment outcomes in patients who cannot receive radiation therapy.

Important Considerations

When treating childhood ependymoma, it's essential to consider the following factors:

• Age: Treatment approaches may vary depending on the age of the child.
• Tumor Location and Size: The location and size of the tumor can impact treatment decisions.
• Other Health Conditions: Children with other health conditions may require special consideration when developing a treatment plan.
