The Cavum Septi Pellucidi
Objective. The cavum septi pellucidi (CSP) is routinely imaged in the fetal brain during obstetric sonography; in fact, for well over a decade, assessment of the CSP has been considered part of the required elements of a standard examination of fetal morphology in guidelines developed by multiple specialty societies. Our objective is to present the 4 reasons why all practicing sonologists and s...
متن کاملCavum septi pellucidi and cavum vergae
The septum pellucidum is a non-neural dual membrane structure originating from the medial parts of the cerebral hemispheres. Right and left leaves of the septum are separated by a cavity in fetal life, which gradually becomes thinner and obliterated. Its posterior extension is the cavum vergae. The roof is formed by the corpus callosum and the hippocampal commissure, and posterior and inferior ...
متن کاملAssessment of corpus callosum biometric measurements at 18 to 32 weeks' gestation by 3-dimensional sonography.
OBJECTIVES The purposes of this study were to construct reference limits for corpus callosum dimensions measured on images reconstructed from 3-dimensional (3D) sonography and to evaluate the reproducibility of these measurements. METHODS Three-dimensional sonographic volumes were acquired transabdominally from an axial view of the head in 361 fetuses cross-sectionally studied at 18 to 32 wee...
متن کاملNon-visualisation of cavum septi pellucidi: implication in prenatal diagnosis?
OBJECTIVE This manuscript reviews congenital anomalies and imaging findings associated with non-visualisation of the cavum septi pellucidi (CSP) found on prenatal sonogram. BACKGROUND Observation of a normal cavum septi pellucidi (CSP) is an important landmark in the second and third trimester prenatal ultrasound evaluation of the fetal brain, and its visualisation provides reassurance of nor...
متن کاملColumns of the fornix, not to be mistaken for the cavum septi pellucidi on prenatal sonography.
OBJECTIVE Visualization of the cavum septi pellucidi (CSP) is considered an integral part of the prenatal second-and third-trimester sonographic evaluations of the fetal neural axis. We have noted that another anatomic structure, the columns of the fornix, can be mistaken for the CSP and result in the missed diagnosis of agenesis of the corpus callosum. METHODS We describe a case in which the...
