Cerebral herniation
Cerebral herniation: The abnormal protrusion of brain tissue through an opening when there is increased intracranial pressure (when the brain is under increased pressure). The increased pressure may be due to a number of causes including inflammation of the brain (as in meningitis), a tumor, hemorrhage, and edema (swelling of the brain). The tonsils of the cerebellum, for example, may be forced from their normal position (within the posterior fossa of the skull) through the foramen magnum into the vertebral canal. This is usually fatal.

spastic, choreoathetoid, and hypotonic (flaccid). In spastic CP, there is an abnormality of muscle tone in which one or more extremities (arms or legs) are held in a rigid posture. Choreoathetoid CP is associated with abnormal, uncontrollable writhing movements of the arms and/or legs. A child with hypotonic CP appears floppy’like a rag doll. Treatment […]
- Cerebral ventricle
Cerebral ventricle: One of a system of four communicating cavities within the brain that are continuous with the central canal of the spinal cord. They include two lateral ventricles in the cerebral hemispheres, each consisting of a triangular central body and four horns. The lateral ventricles communicate with the third ventricle through an opening called […]

Cerebrohepatorenal syndrome: A genetic disorder, which is also called the Zellweger syndrome, characterized by the reduction or absence of peroxisomes (cell structures that rid the body of toxic substances) in the cells of the liver, kidneys, and brain. Zellweger syndrome is one of a group of disorders called the leukodystrophies, all of which affect the […]
