Bilateral ventriculomegaly_Bilateral ventriculomegaly

Everyone has a brain. Inside the brain are not only brain nerves, but also brain matter and soft tissue of the brain. The most important brain nerve functions of people are affected, so the brain cannot be damaged under normal circumstances. Once it is hit, problems will arise. Some people will find out that the side of the cerebral ventricle is dilated when they are examined in the hospital. This result needs to be clearly diagnosed and the structure needs to be understood clearly.

Bilateral ventriculomegaly

structure

Each lateral ventricle has three horns:

The anterior or frontal angle of the

occipital lobe

Move the inferior or temporal horn to the temporal lobe

The body of the lateral ventricle is the central portion, just posterior to the anterior horn. The trigone of the lateral ventricle is a triangular area defined by the temporal horn inferiorly, the occipital horn posteriorly, and the body of the lateral ventricle anteriorly. The CELLA media is the central part of the lateral ventricle. The ependyma covers the interior of the lateral ventricles and is an epithelial cell.

develop

The lateral ventricles, like the rest of the ventricular system of the brain, develop from the central canal of the neural tube. Specifically, the lateral ventricles originate from the portion of the tube present in the developing forebrain in the developing telencephalon, and subsequently, during the first trimester of gestation the central canal expands into the lateral, third, and fourth ventricles, connected by thinner channels. In the lateral ventricles, specialized areas - the choroid plexus - appear, which produce cerebrospinal fluid. If its production is greater than its reabsorption or its circulation is blocked- enlargement of the ventricles may occur and lead to hydrocephalus. Fetal lateral ventricles can be diagnosed using either linear or planimetric measurements.

Clinical significance

It is known that the volume of the lateral ventricles increases with age. Patients with some neurological disorders, such as schizophrenia, bipolar disorder, depression, and Alzheimer's disease, have larger average lateral ventricle volumes than normal.

Lateral ventricle tumor

Lateral ventricle tumors are not difficult to diagnose based on their special clinical manifestations and the results of auxiliary examinations, but they are easily confused with the following diseases and need to be differentiated.
