Cerebral Edema that resulted from brain tumor is represented by darker areas on this CT image. An increase in cerebral water content is called cerebral edema and it usually results from traumatic brain injury (TBI), subarachnoid hemorrhage (SAH), intracerebral hemorrhage (ICH), subdural hematoma, ischemic stroke, brain tumors, infectious disorders and intracranial surgery.
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.
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]
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.
It is called tumefactive as the lesions are "tumor-like" and they mimic tumors clinically, radiologically and sometimes pathologically. [1] 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 ...
Diffuse midline glioma, H3 K27-altered (DMG) is a fatal tumour that arises in midline structures of the brain, most commonly the brainstem, thalamus and spinal cord.When located in the pons it is also known as diffuse intrinsic pontine glioma (DIPG).
Medulloblastoma is a common type of primary brain cancer in children. It originates in the part of the brain that is towards the back and the bottom, on the floor of the skull, in the cerebellum, or posterior fossa. [3] The brain is divided into two main parts, the larger cerebrum on top and the smaller cerebellum below towards the
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 ...
