Cavum velum interpositum Image
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.
Radiology MRI Cavum Velum Interpositum on MRI
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 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 .
Arachnoid Cyst of the Cavum Velum Interpositum in a Septuagenarian Radiological Features and
The velum interpositum is the double-layered tela choroidea of the third ventricle. It is located anteroinferior to the splenium of the corpus callosum and below the columns of the fornix 1. It is bordered anteriorly by the foramen of Monro and posteriorly by the pineal body.
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 cyst Radiology Case
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 septum pellucidum, cavum vergae, and cavum veli interpositi (annotated CT) Image
The velum interpositum is a small membrane containing a potential space just above and anterior to the pineal gland which can become enlarged to form a cavum veli interpositi . Gross anatomy The velum interpositum is formed by an invagination of pia mater forming a triangular membrane the apex of which points anteriorly.
Cavum velum interpositum cyst Image
The interhemispheric cyst-like structure observed on fetal brain ultrasound imaging at 14-17 weeks is a physiologic transient cavum veli interpositi (CVI). The early CVI is located dorsal to the internal cerebral veins and is present in half of normal fetuses, as part of normal midline development. What are the clinical implications of this work?
Intracranial Cysts and Cystic Lesions ASN Annual Meeting
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 Image
T1 Axial T1 C+ Sagittal FLAIR A triangular shaped cystic space is present in the midline, immediately below the splenium of corpus callosum, displacing the fonices up, and internal cerebral veins down. It follows CSF on all sequences. Features are characteristic of a cavum velum interpositum cyst. Case Discussion
Cavum velum interpositum cyst Radiology Case
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.
