A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [2] Common symptoms of CNS tumors include vomiting, headache, changes in vision, nausea, and seizures. [3]
The most common brain tumor types in children (0–14) are: pilocytic astrocytoma, malignant glioma, medulloblastoma, neuronal and mixed neuronal-glial tumors, and ependymoma. [106] In children under 2, about 70% of brain tumors are medulloblastomas, ependymomas, and low-grade gliomas.
Medulloblastoma is the second-most frequent brain tumor in children after pilocytic astrocytoma [37] and the most common malignant brain tumor in children, comprising 14.5% of newly diagnosed brain tumors. [38] In adults, medulloblastoma is rare, comprising fewer than 2% of CNS malignancies. [39]
If you were to pick a case to illustrate the abrupt, random, frightening nature of brain tumors, it might be the experience of Maria Menounos. The 41-year-old TV personality discovered she had a ...
The main subtypes of brain and central nervous system tumors in children are: astrocytoma, brain stem glioma, craniopharyngioma, desmoplastic infantile ganglioglioma, ependymoma, high-grade glioma, medulloblastoma and atypical teratoid rhabdoid tumor. [40] Other, less common childhood cancer types are: [40] [38] Neuroblastoma (6%, nervous system)
For children experiencing seizures, an EEG might be part of the diagnostic process (the goal being to record the brain's electrical activity in order to identify and localize seizure activity). Finally, a biopsy of the tumor, taken through a needle during a simple surgical procedure, helps to confirm the diagnosis.
Pilocytic astrocytoma (and its variant pilomyxoid astrocytoma) is a brain tumor that occurs most commonly in children and young adults (in the first 20 years of life). They usually arise in the cerebellum, near the brainstem, in the hypothalamic region, or the optic chiasm, but they may occur in any area where astrocytes are present, including the cerebral hemispheres and the spinal cord.
A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord. They are malignant but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumors, and 80 percent of all malignant brain tumors. [4]
