Cavum velum interpositum cyst Image
The velum interpositum (VI) is a membrane resulting from the superposition of two layers of the tela choroidea of the third ventricle demarcating a potential space containing cerebrospinal fluid (CSF) located in the region between the internal cerebral veins (ICV) and the posterior medial choroidal artery.

Within the region of the velum interpositum or transverse cerebral fissure, three paired structures can be visualised in imaging studies: crura of fornices, internal cerebral veins and thalamic striae with choroid plexus of the third ventricle (Fig. 1).Very often the diverging crura of fornices under the splenium of corpus callosum are captured on the axial pictures as formation resembling.
Cavum velum interpositum cyst Radiology Case
The cavum veli interpositi is within the double-layered tela choroidea of the third ventricle, not superior to it. The internal cerebral veins are within the cavum veli interpositi, not inferior to it. The correct nomenclature is velum interpositum and cavum veli interpositi.
Cavum Velum Interpositum on MRI
The internal cerebral veins are situated between the two layers of the cavum velum interpositum as is the posterior medial choroidal artery . On axial imaging, the cavum velum interpositum has a distinct triangular appearance with an apex directed anteriorly toward the forniceal columns (Fig. 1). An enlarged cavum velum interpositum displaces.

Cavum velum interpositum cyst Radiology Case
A cavum veli interpositi (CVI), often incorrectly termed a cavum velum interpositum , is an anatomic variation where there is a dilatation of the normal cistern of the velum interpositum .

To describe a fetal cavum velum interpositum cyst (CVIC) and to review its clinical significance. Methods. Description and follow-up of two cases with prenatal diagnosis of a midline cyst in the fetal brain, at the Chaim Sheba Medical Center. The cases were reviewed and followed-up by a multidisciplinary team that included.
Cavum velum interpositum Image
Cavum veli interpositi is a rare anatomical variation characterized by an enlarged space within the velum interpositum, a structure located between the two layers of the tela choroidea in the brain. This article aims to provide a comprehensive understanding of cavum veli interpositi, including its anatomy, clinical significance, and associated conditions.
Cavum velum interpositum cyst Radiology Case
The cavum velum interpositum (CVI), considered a normal variant, is a true cistern situated above the third ventricle. It may or may not communicate with the ventricular system. Key Diagnostic Features: CT or MR imaging demonstrates CSF density/intensity cystic appearing lesion between the atria of the lateral ventricles.

The velum interpositum (VI) is a membrane resulting from the superposition of two layers of the tela choroidea of the third ventricle demarcating a potential space containing cerebrospinal fluid (CSF) located in the region between the internal cerebral veins (ICV) and the posterior medial choroidal artery. Kruse, in 1930 defined the dilatation.

Cavum velum interpositum cyst Radiology Case
The velum interpositum is usually a closed space that tapers to a narrow apex just behind the foramen of Monro. It may have opening that communicates with the quadrigeminal cistern to form the velum interpositum cistern. There may also be a space above the velum interpositum between the hippocampal commissure and splenium called the cavum vergae.
Cavum velum interpositum cyst Image
Introduction: Anterior midline intracranial cysts may be found most often in three forms: cavum septum pellucidum, cavum vergae, and cavum velum interpositum. A single offering that reviews these entities is difficult to find in the extant literature. Therefore, the present review was performed.

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.
