Ventriculomegaly is a brain condition that mainly occurs in the fetus when the lateral ventricles become dilated. The most common definition uses a width of the atrium of the lateral ventricle of greater than 10 mm. [1] This occurs in around 1% of pregnancies. [2]
Hydrocephalus is usually due to blockage of CSF outflow in the ventricles or in the subarachnoid space over the brain. In a person without hydrocephalus, CSF continuously circulates through the brain, its ventricles and the spinal cord and is continuously drained away into the circulatory system. Alternatively, the condition may result from an ...
Colpocephaly is a cephalic disorder involving the disproportionate enlargement of the occipital horns of the lateral ventricles and is usually diagnosed early after birth due to seizures. It is a nonspecific finding and is associated with multiple neurological syndromes , including agenesis of the corpus callosum , Chiari malformation ...
The volume of the lateral ventricles is enlarged in some neurological diseases, such as schizophrenia, [8] bipolar disorder, [9] major depressive disorder, [9] and Alzheimer's disease. [10] Ventriculomegaly is a brain condition that mainly occurs during development when the lateral ventricles become dilated. [11]
The septum pellucidum is a thin, triangular, vertical membrane separating the anterior horns of the left and right lateral ventricles of the brain. It runs as a sheet from the corpus callosum down to the fornix. During fetal development at approximately the twelfth week of gestation, a space forms between two laminae, which is the CSP. At ...
Images showing an enlarged third ventricle along with a normally sized fourth ventricle (in a lateral view) is generally considered to be an indication of aqueductal stenosis, but this is still only presumption. [2] [3] CT scans are typically used after a shunt treatment in order to analyze ventricle size and determine if the device is working ...
With a potential government shutdown looming ahead of the holidays, here's what you need to know if mail services will be impacted by it.
Axial MR/CT show a triangular-shaped cerebrospinal fluid (CSF) space between the lateral ventricles. On sagittal images, CVI can appear as a slit-like, linear-to-round/ovoid CSF collection below the fornices, and above the 3rd ventricle. There are usually no associated abnormalities, although larger lesions may cause an obstructive ...
