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]
Increased intracranial pressure was also found in the condition. Similar symptoms (absence of corpus callosum and increased head circumference) were noted as in the case of colpocephaly that is associated with microcephaly. A bi-ventricular peritoneal shunt was performed, which greatly improved the symptoms of the condition.
It shows enhancement of meninges at the tentorium and in the parietal region, with evidence of dilated ventricles. Fluid-attenuated inversion recovery (FLAIR) is a magnetic resonance imaging sequence with an inversion recovery set to null fluids.
In the brain, the cavum veli interpositi (CVI) is a condition in which the cistern of the velum interpositum becomes dilated. The phenomenon usually occurs in newborns. Axial MR/CT show a triangular-shaped cerebrospinal fluid (CSF) space between the lateral ventricles.
A water-based gel is applied to the infant's head, over the anterior fontanelle, to aid conduction of ultrasound waves. Ideally scans are performed during sleep or when the infant is calm. The operator then uses an ultrasound probe to examine the baby's brain, viewing the images on a computer screen and recording them as necessary. [citation ...
The preliminary diagnosis of PVL is often made using imaging technologies. In most hospitals, premature infants are examined with ultrasound soon after birth to check for brain damage. Severe white matter injury can be seen with a head ultrasound; however, the low sensitivity of this technology allows for some white matter damage to be missed.
Dilated cardiomyopathy is when the muscle walls of your heart become stretched and can’t pump blood properly. It can be caused by inherited genes, chronic conditions, and unhealthy lifestyle habits.
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 ...
