EP08.13: Outcome of prenatally diagnosed cavum velum interpositum (CVI) cyst

Sonographic characteristics of the cavum velum interpositum.

BACKGROUND AND PURPOSE Differential considerations for pineal region CSF collections include both true cysts and normal cystlike anatomic variations. Our purpose was to determine the sonographic characteristics of pineal region fluid spaces that reflect the presence of a normal persistent cavum velum interpositum (CVI). METHODS Eighteen neonates and infants who had sonographic findings of "cy...

Arachnoid cyst of the velum interpositum.

Arachnoid cysts are thin-walled fluid-filled cavities that are uncommon causes of intracranial mass lesions [1 , 2]. These lesions have been found in various locations, both supratentorial and infratentorial [1 , 3-7] . This report describes a case in which the arachnoid cyst arose from the tela choroidea and occupied the cistern of the velum interpositum. The cyst caused symptoms similar to th...

Peripartal management of a prenatally diagnosed large oral cyst

Case Report: Infant with prenatally diagnosed arachnoid cyst

Case This patient’s central nervous system abnormality was first suspected during a routine prenatal ultrasound at 29 weeks gestation. It was discovered that the patient had ventriculomegaly and a pineal region cyst (Figure 1a). A fetal MRI was performed at 31 weeks gestation (Figure 2). This showed a 3x3x3 cm unilocular cyst in the quadrigeminal plate cistern causing obstructive hydrocephalus....
