What does it mean if they cant find the cavum septum pellucidum in an ultrasound?

Non-visualisation of the CSP is a prenatal sonographic finding, which in most cases is associated with neuroanatomical anomalies that include agenesis of the corpus callosum, schizencephaly, septo-optic dysplasia, holoprosencephaly, chronic hydrocephalus and acquired fetal brain injury.

What does CSP mean in ultrasound?

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.

What surrounds the septum pellucidum?

The anterior or frontal horn is located anterior to the interventricular foramen. The floor and the lateral wall are formed by the head of the caudate nucleus, the corpus callosum constitutes the roof and anterior border, and the septum pellucidum delineates the medial wall.

What is enlarged cavum septum pellucidum?

An enlarged cavum septum pellucidum was defined as a cavum length of ≥6 mm. Groups without, with persistent, and with enlarged cavum septi pellucidi were compared for brain structure volumes, nonverbal intelligence, and emotional and behavioral problems.

What is the role of the septum pellucidum?

The septum pellucidum separates the frontal horns and body of the ventricle in the midline. The septum pellucidum is attached superiorly to the body of the corpus callosum and anteriorly to the genu of the corpus callosum. It is important to pay attention to the inferior attachment of the septum pellucidum.

What happens if you don’t have septum pellucidum?

Specifically, a thin membrane called the septum pellucidum is missing from its normal position in the middle of the brain. When it is missing, symptoms may include learning difficulties, behavioral changes, seizures , and changes in vision. Absence of the septum pellucidum is not typically seen as an isolated finding.

What causes cavum septum pellucidum?

CSP has been loosely associated with schizophrenia, post-traumatic stress disorder, traumatic brain injury, as well as with antisocial personality disorder. CSP is one of the distinguishing features of individuals displaying symptoms of dementia pugilistica (chronic traumatic encephalopathy).

Does the brain have a septum?

The septum pellucidum (SP) is a thin membrane located at the midline of the brain between the two cerebral hemispheres, or halves of the brain. It is connected to the corpus callosum — a collection of nerve fibers that connect the cerebral hemispheres.

How common is cavum septum pellucidum?

A persistent CSP with a cavum length of <5 mm is common in a large proportion of healthy subjects, with prevalence rates of up to 30% in the adult population,1,4 and is therefore considered a normal variant. In general, the size of a normal-variant septum is estimated at approximately 1–4 mm.

What does cavum septum pellucidum do?

In post-natal life, the laminae of the septum pellucidum usually fuse, which obliterates the cavum. The cavity contains cerebrospinal fluid (CSF) that filters from the ventricles through the septal laminae.
