Jul 6, 2024 · The lateral ventricles are paired CSF-filled spaces in the cerebrum and part of the ventricular system of the brain. They are larger than the third or fourth ventricles but can be asymmetrical. Each has five divisions, including three horns that project into the lobe after which they are named: anterior/frontal horn. inferior/temporal horn. body

Oct 13, 2024 · The lateral ventricles occasionally show small side to side differences in size on CT or MRI of the brain. This asymmetry of the lateral ventricles (ALV) is an anatomic variant in most cases.

Jul 29, 2024 · Ventricles contain around 20% of the total average adult CSF volume, around 20-25 mL. The ventricular system consists of four ventricles (spaces), two being midline and the other two being paired: right and left lateral ventricles. a midline third …

Oct 18, 2024 · The ventricle is focally expanded. Any part of the ventricle proximal to it (e.g. the temporal horn of the lateral ventricle in lesions of trigone) may be dilated due to outflow obstruction. CT ventriculography may be of benefit although seldom used since the advent of high-resolution MRI.

Jul 14, 2024 · Ring-shaped lateral ventricular nodules (RSLVNs) are small nodular ring-shaped lesions attached generally to the ependyma of the roof and body of the lateral ventricles. They are incidental findings and are of no reported clinical significance 1 .

Nov 1, 2024 · The ventricle is measured from inner margin of the medial ventricular wall to inner margin of the lateral wall. Fetal ventriculomegaly is defined as: >10 mm across the atria of the posterior or anterior horn of lateral ventricles at any point in the gestation

Feb 13, 2025 · Intraventricular neoplasms are rare and arise from periventricular structures such as the walls of the ventricular system, the septum pellucidum and the choroid plexus. Many tumor types arise from or can bulge into the ventricular system, although there are certain lesions that are relatively restricted to ventricles.

Dec 14, 2024 · Slit ventricle syndrome, sometimes known as symptomatic ventricular coaptation, refers to a constellation of symptoms associated with abnormally small ventricles. Although it is most commonly seen in the setting of CSF diversion, it is not synonymous with CSF overdrainage .

May 21, 2024 · The anteroposterior diameter of the lateral ventricle index (ALVI) is a quantitative metric to evaluate the size of the lateral ventricles, particularly in normal pressure hydrocephalus.

Oct 18, 2024 · Colpocephaly is a descriptive term for a disproportionate prominence of the occipital horns of the lateral ventricles. It can result from a wide range of congenital insults.
