Ventriculomegaly What is ventriculomegaly?
produced in the brain ventricles and circulates around the brain and spinal cord, protecting them from injury and supplying brain cells with nutrients. Hydrocephalus can occur due to impaired circulation or malabsorption and is a medical emergency, which can lead to raised intracranial pressure. Nurses are responsible for the care of

entire surface of the brain and spine cord is bathed by a clear, colorless fluid called cerebrospinal fluid (CSF). Cerebrospinal fluid is a clear, watery liquid that surrounds the brain and spinal cord, and is also found throughout the ventricles (brain cavities and tunnels). …

Ependymoma: • Arise from ependymal cells or ependymal cell rests. • > 60% are located in the fourth ventricle • More common in children than adults • "Soft" tumor which accommodates to shape of cisterns or ventricles and often extends into cerebellar pontine angle or cisterna magna. • Heterogeneous on CT often with calcifications • On MRI is T1 isointense and T2 hyperintense

brain. The ventricles are connected to the spinal cord and the covering of the brain. These connections let fluid flow through the baby’s brain and spine. If fluid is not flowing in the usual way, it can build-up in the ventricles. In other cases, a problem in the way the brain formed leaves extra …

- The ventricles are lined by ependymal cells which are modified glial cells. As these cells are not fused by tight junctions, free exchange exists between the cerebrospinal fluid containing ventricles and the extracellular space of the brain. Typically, this situation permits the washout of many products of brain

In the brain there are five interconnected fluid-filled cavities. These are called ventricles. The ventricles produce and are filled with cerebro-spinal fluid; from the ventricles the cerebro-spinal fluid circulates into the central spinal canal. During a routine ultrasound investigation, the width of the posterior part (‘posterior horn’ or ...

malacia, brain malformations, and hydrocephalus. To establish the presence of hydrocephalus the size of the ventricular system, especially the lateral ventricles, must be known. Measurements of normal ventricular size in adults and children over 1 year have been widely reported [1-5], but only a few papers deal with ventricular
