| 释义 |
| Name = Cavum veli interpositi | Latin = | Image = Cavum.jpg | Caption = Difference between cavum septi pellucidi (CSP), cavum Vergae (CV), and cavum veli interpositi (CVI). 3=third ventricle, 4=fourth ventricle. | System = | Artery = | Vein = }} 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. 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 hydrocephalus. No treatment is usually necessary.[1] See also
