A cervico-medullary low-grade glioma is a tumor arising from a type of cell of the central nervous system known as a glial cell. These tumors originate from a specific type of glial cell known as an astrocyte. Astrocytes make up the supportive network of the brain. These cells are named for their star-like appearance. Cervico-medullary low-grade gliomas are astrocytomas (grade I pilocytic astrocytomas or grade II fibrillary astrocytomas) that arise from the junction of the brain and spinal cord.

Children with certain genetic syndromes, including neurofibromatosis and tuberous sclerosis, are at higher risk of developing tumors of glial origin, including cervico-medullary low-grade gliomas. The vast majority of children with cervico-medullary low-grade gliomas, however, develop these tumors spontaneously, meaning these is no identifiable cause.

Due to the relative slow growth rate of cervico-medullary low-grade gliomas, children with these tumors tend to present to the doctor with symptoms that have been occurring for many months. Some children, however, have a more sudden onset of symptoms. The following are the most common symptoms of a cervico-medullary low-grade glioma, however, each child may experience symptoms differently. Common symptoms may include:
|
|
|
- many present with symptoms of increased pressure within the brain. These symptoms include:
- headache (generally upon awakening in the morning)
- vomiting
- fatigue
- some may have neck discomfort and difficulty moving some of all of the limbs of the body
|
|
|
|
The symptoms of a brain tumor may resemble other conditions or medical problems. Always consult your child's physician for a diagnosis.

Diagnostic procedures for a cervico-medullary low-grade glioma may include:
|
|
|
- physical examination - the child may demonstrate increased pressure in the brain or difficulty moving the neck or arms
- computerized tomography scan (also called a CT or CAT scan) - a diagnostic imaging procedure that uses a combination of x-rays and computer technology to produce cross-sectional images (often called slices), both horizontally and vertically, of the body. CT scans are more detailed than general X-rays. For cervico-medullary low-grade gliomas, a CT scan of the brain is usually done.
- magnetic resonance imaging (MRI) - a diagnostic procedure that uses a combination of large magnets, radiofrequencies, and a computer to produce detailed images of organs and structures within the body. For cervico-medullary low-grade gliomas, an MRI of the brain and spine is usually done.
- biopsy - in many cases, a tissue sample from the tumor will be taken through a needle during a simple surgical procedure performed by a surgeon to confirm the diagnosis

Specific treatment for a cervico-medullary low-grade glioma will be determined by your child's physician based on:
|
|
|
- your child's age, overall health, and medical history
- type, location, and size of the tumor
- extent of the disease
- your child's tolerance for specific medications, procedures, or therapies
- how your child's doctors expects the disease to progress
- your opinion or preference

Treatment may include (alone or in combination):
