  • Malignant cancer cells have a characteristic of growing quickly and spread.
  • The central nervous system embryonal tumours commonly form in the brain cells.
  • The benign brain tumours can grow and press on the nearby areas of the brain.
  • There are four types of central nervous system embryonal tumours.

The central nervous system embryonal tumours are malignant or benign cells that start in the embryonic or fetal cells that remain in the brain post birth. These tumours tend to spread via the cerebrospinal fluid to the other parts of the brain as well as spinal cord. The tumours can be either malignant or benign. Most of the CNS embryonal tumours in children are malignant in nature.

Malignant cancer cells have a characteristic of growing quickly and spread into different parts of the brain. When the tumour grows into or presses on the area of the brain, it can stop that part of the brain from performing or functioning the way it should. The benign brain tumours can grow and press on the nearby areas of the brain and spread to other parts of the brain very slowly. Both benign as well as malignant brain tumours can cause different signs and symptoms.


Even though cancer is a rare condition in children, the brain tumours are the third most common type of cancer occurring in children after lymphoma and leukemia.

Types of CNS

There are different types of CNS embryonal tumours. These include the following:

CNS primitive Neuroectodermal Tumours

These are fast-growing tumours that tend to commonly form in the brain cells inside the cerebrum, which is located at the top of the head and is said to be the largest part of the brain. The cerebrum control different human interactions and activities, such as learning, thinking, emotions, problem-solving, voluntary movement, reading and speech. There are four types of CNS primitive neuroectodermal tumours.

 

  • CNS ganglioneuroblastomas: these are a very rare form of tumours that develop in the nerve tissue of the brain and the spinal cord. These tumours may form in just one area and then grow fast or form in more than one area and gradually grow.
  • CNS Neuroblastomas: these are also rare types of neuroblastoma that develop in the nerve tissue of the cerebrum or the layers of tissue that cover the spinal cord as well as brain. These tumours may be large and can spread to different parts of the spinal cord or brain.
  • Ependymoblastomas:these are fast-growing tumours that form inside the brain cells that line the fluid-filled spaces inside the spinal cord and brain. These usually tend to form near the tailbone.
  • Medulloepitheliomas: these are fast-growing tumours that develop inside the brain cells that line the tube-like space inside the spinal cord and brain.

Medulloblastomas

Most of the CNS embryonal tumours are medulloblastomas. These are fast-growing tumours that form in the brain cells inside the cerebellum. This cerebellum is located at the rear of the brain i.e. between the brain stem and the cerebrum. The cerebellum is said to control movement, posture and balance. The medulloblastomas tends to spread to the bone, lung, bone marrow or other parts of the body, but this is a rare medical condition.
