Cavum velum interpositum cyst Radiology Case
The cavum velum interpositum ( * ) is a triangular space in axial section located below the fornices (green) and above the internal cerebral veins (blue) and thus also above the pineal gland (yellow). 2 case questions available Case Discussion
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.
Learning Neuroradiology Case 1404 Cavum septum pellucidum / vergae / 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.

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.
Radiology MRI Cavum Velum Interpositum on MRI
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 .
Cavum velum interpositum cyst Radiology Case
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 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.
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.
Cavum velum interpositum cyst Radiology Case
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 on MRI
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.

Cavum velum interpositum Image
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
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 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?

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.
Cavum velum interpositum cyst 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.
