What does enlarged cavum septum pellucidum mean?

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 causes CSP?

Cause. The cause of CSP is basically unknown, although it is thought that prenatal alcohol exposure plays a significant role.

What does CSP mean in ultrasound?

ABSTRACT : OBJECTIVE. Screening the cavum septi pellucidi (CSP), more commonly referred to as the “cavum septum pellucidum,” is a required component of the fetal anatomic survey during second-trimester ultrasound (US).

Is cavum septum pellucidum normal?

The cavum septum pellucidum (CSP) is a potential cavity between the membranous leaves of the septum pellucidum, separated by at least 1 mm, and is considered a normal anatomical variation.

What does the septum do in the brain?

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.

Can you live without a cavum septum pellucidum?

By itself, absence of the septum pellucidum is not life-threatening. When the absence of the septum pellucidum is part of septo-optic dysplasia, the prognosis varies according to the presence and severity of associated symptoms.

When does the CSP develop?

The cavum septi pellucidi (CSP) is an important landmark in evaluation of the fetal brain and has become integral to both routine and detailed ultrasound examinations1. Development of the CSP begins at c. 10–12 weeks and it is fully formed by 17 weeks of gestation2.

What is a cavum septum?

A cavum septum pellucidum is a cerebrospinal fluid (CSF) filled cavity situated between the lateral ventricles and is considered as a normal anatomic variant sporadically seen on neuroimaging.

What is cavum septum pellucidum in fetus?

The cavum septum pellucidum (CSP) is a fluid-filled cavity situated between the membranes which form the septum pellucidum (Figure 1). It is commonly demonstrated with ultrasound in the second- and third-trimester fetus in most premature infants and in about 50% of full-term infants1±3.

What is the normal size cavum septum pellucidum?

Mean CSP width was 5.3 +/- 1.7 mm (range 2-9 mm). The CSP width increased with gestational age and BPD but with a slight decrease around term. Conclusions: In normal fetuses the CSP should always be visualized between 18 and 37 weeks, or with a BPD of 44-88 mm.

When can you see CSP on ultrasound?

In conclusion, our experience indicates that, in normal fetuses, the CSP should always be visualized by standard transabdominal ultrasound between 18 and 37 weeks, or with a BPD of 44±88 mm.
