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.
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.
The interthalamic adhesion (also known as the massa intermedia, intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle.

Tumors located in the lower part of the cerebrum near the primary visual cortex can cause blurred vision, double vision, or loss of vision. Tumors located in the spinal cord usually have symptoms that start with back pain that spreads towards the arms or legs. These tumors can cause trouble urinating or walking.
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.
In adult patients, the overall two-year survival rate is 19.7%, with low grade tumors holding a two-year survival rate of 31.0% and high-grade tumors holding a two-year survival rate of 16.5%. [2] In pedtiatric patients, low-grade astrocytomas held a five-year survival rate of 40% while high-grade astrocyte tumors held a five-year survival rate ...
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
