    en.wikipedia.org/wiki/Dysembryoplastic_neuro...

    Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.

    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.

    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]

  6. Encephalization quotient - Wikipedia

    en.wikipedia.org/wiki/Encephalization_quotient

    Encephalization quotient (EQ), encephalization level (EL), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species.

  7. Tumefactive multiple sclerosis - Wikipedia

    en.wikipedia.org/wiki/Tumefactive_multiple_sclerosis

    These atypical lesion characteristics include a large intracranial lesion of size greater than 2.0 cm with a mass effect, edema and an open ring enhancement. A mass effect is the effect of a mass on its surroundings, for example, exerting pressure on the surrounding brain matter. Edema is the build-up of fluid within the brain tissue.

  8. WHO classification of tumours of the central nervous system

    en.wikipedia.org/wiki/WHO_classification_of...

    The 5th WHO classification delineates distinct types of tumors, some of them being further divided into subtypes, rendering the former terms entity and variant obsolete. When molecular diagnostics are not complete enough to allow precise classification, diagnosis should be designated by appending not otherwise specified (NOS).

  9. Vestibular schwannoma - Wikipedia

    en.wikipedia.org/wiki/Vestibular_schwannoma

    The Central Brain Tumor Registry of the United States, established in 1992, only began to keep records for benign tumors like VS in 2004. In 2006, a landmark study from Denmark, entitled "The Natural History of Vestibular Schwannoma," [ 3 ] initiated a significant trend toward observation for managing small VS.
