The prognosis for a subependymoma is better than for most ependymal tumors, [3] and it is considered a grade I tumor in the World Health Organization (WHO) classification. They are classically found within the fourth ventricle , typically have a well demarcated interface to normal tissue and do not usually extend into the brain parenchyma ...

This is a shortened version of the second chapter of the ICD-9: Neoplasms. It covers ICD codes 140 to 239 . The full chapter can be found on pages 101 to 144 of Volume 1, which contains all (sub)categories of the ICD-9.
Subependymal giant cell astrocytoma (SEGA, SGCA, or SGCT) is a low-grade astrocytic brain tumor (astrocytoma) that arises within the ventricles of the brain. [1] It is most commonly associated with tuberous sclerosis complex (TSC). Although it is a low-grade tumor, its location can potentially obstruct the ventricles and lead to hydrocephalus.
The concept of grading of the tumors of the central nervous system, agreeing for such the regulation of the "progressiveness" of these neoplasias (from benign and localized tumors to malignant and infiltrating tumors), dates back to 1926 and was introduced by P. Bailey and H. Cushing, [1] in the elaboration of what turned out the first systematic classification of gliomas.
Astrocytoma is a type of brain tumor.Astrocytomas (also astrocytomata) originate from a specific kind of star-shaped glial cell in the cerebrum called an astrocyte.This type of tumor does not usually spread outside the brain and spinal cord and it does not usually affect other organs.
