“Brain Neoplasms (Brain Tumors)”  

Brain Neoplasms

  In our body's brain, Brain Tumor (Brain Neoplasm) is a central nervous system neoplasm of the intracranial components of the central nervous system, including the cerebral hemispheres, basal ganglia, hypothalamus, thalamus, brain stem, and cerebellum.
  In our body, Brain Tumor (Brain Neoplasm) is an infectious associated disease linked or correlated with at least one infectious pathogen, and indicative to a specific set of signs, symptoms or other health indicators, associated with a health challenge.
  Examples of related brain neoplasms and dis-orders include:

• cerebral ventricle neoplasms
  • choroid plexus neoplasms
    • choroid plexus papilloma
• infratentorial neoplasms
• neurocytoma
• pinealoma
• supratentorial neoplasms
  • hypothalamic neoplasms
    • Pallister-Hall syndrome
    • pituitary neoplasms

In our body, brain tumors may be graded based on how aggressive the tumor cells appear under a microscope, featuring four distinct grades:

• Grade I brain cancer, tumors grow slowly, rarely spreading into nearby tissues
• Grade II brain cancer, tumors grow slowly, but may spread into nearby tissue or recur
• Grade III brain cancer, the tumors grow quickly, likely to spread into nearby tissues with the tumor cells not looking like normal cells
• Grade IV brain cancer, the tumors grow very quickly and spread very quickly, with the tumor cells not looking like normal cells

“Cerebral Ventricle Neoplasms (Cerebral Ventricle Tumors)”  

Cerebral Ventricle Neoplasm

  In our body's brain, Cerebral Ventricle Neoplasms are neoplasms located in the brain ventricles, including the two lateral, the third, and the fourth ventricle, indicative to a specific set of signs, symptoms or other health indicators, associated with a brain ventricle health challenges.
  Examples of related cerebral ventricle neoplasms include:

• choroid plexus neoplasms
  • choroid plexus papilloma (WHO grade I)
  • Atypical Choroid Plexus Papilloma (WHO grade II)
  • Choroid Plexus Carcinoma (WHO grade III)

“Infratentorial Neoplasms”  

  In our body's brain, Infratentorial Neoplasms are intracranial brain tumors originating in the region of the brain inferior to the tentorium cerebelli, which contains the cerebellum, fourth ventricle, cerebellopontine angle, brain stem, and related structures.
  Examples of related infratentorial neoplasms include:

• Infratentorial Cancer
• Benign Infratentorial Neoplasms

• brain stem neoplasms
• cerebellar neoplasms (cerebellar tumors)

“Neurocytoma”  

  In our body, Neurocytoma, as a neuroepithelial neoplasm, is a benign brain tumor, composed of neural elements, which most often arise from the septum pellucidum and the walls of the lateral ventricles.
  In our body, Neuroepithelial Neoplasms are neuroectodermal neoplasms (tumors) composed of neural epithelium (neuroepithelial cells) which may differentiate into neurons, oligodendrocytes, or astrocytes.
  Example of a neurocytoma includes:

• Central Neurocytoma

“Pinealoma”  

  In our body's CNS system, Pinealoma, as neuroepithelial neoplasms are brain neoplasms, which originate from pineal parenchymal cells that tend to enlarge the gland and be locally invasive.
  The Pinealoma tumors occasionally seed the neuroaxis or cause obstructive hydrocephalus or Parinaud's syndrome. Germinoma, carcinoma, embryonal, glioma, and other neoplasms may arise in the pineal region with germinoma being the most common pineal region tumor.
  In our body, two major forms of Pinealoma tumors are

• pineocytoma and the more malignant
• pineoblastoma

“Supratentorial Neoplasms”  

  In our body's brain, Supratentorial Neoplasms are primary and metastatic (secondary) tumors of the brain, located above the tentorium cerebelli, indicative to a specific set of signs, symptoms or other health indicators, associated with a health challenge.
  Examples of supratentorial neoplasms related dis-orders include:

• hypothalamic neoplasms
  • Pallister-Hall syndrome
  • pituitary neoplasms

“Gliomas”  

Glioma

  In our body's, brain Glioma refers to tumors that arise from the support cells in the brain, called glial cells.

Glioma tumors

  In our body, Glioma tumors include the astrocytomas, ependymomas and oligodendrogliomas. These tumors are the most common primary brain tumors.
In our body, the neoplasms, Glioma indicative to a specific set of signs, symptoms or other health indicators, associated with central nervous system neoplasms derived from glial cells.
  Examples of related gliomas include:

1. astrocytoma +
2. ependymoma
   • subependymal astrocytoma (subependymal glioma)
3. ganglioglioma
4. gliosarcoma
5. medulloblastoma
6. oligodendroglioma
7. optic nerve glioma (optic pathway glioma) **
