Summary
Familiarity with the cavum septi pellucidi (CSP) is crucial for sonologists and sonographers. Recognizing the CSP confirms normal central forebrain development and aids in diagnosing various neuroanatomic malformations.
Area of Science:
- Obstetric Sonography
- Fetal Neuroimaging
- Developmental Biology
Background:
- The cavum septi pellucidi (CSP) is a standard component of fetal morphology examinations.
- Familiarity with the CSP is essential for obstetric sonologists and sonographers.
- Understanding the CSP's embryology and anatomy is key to accurate diagnosis.
Purpose of the Study:
- To present four key reasons for sonologists and sonographers to be knowledgeable about the CSP.
- To highlight the diagnostic significance of CSP visualization and non-visualization.
- To emphasize the CSP's role in assessing fetal brain development.
Main Methods:
- Review of prenatal sonograms and MRI examinations.
- Analysis of CSP terminology, embryology, and anatomy.
- Examination of pitfalls in CSP identification and associated abnormalities.
Main Results:
- CSP development is linked to the corpus callosum (CC); its presence excludes complete CC agenesis.
- Absence of the CSP is associated with a spectrum of malformations, from lethal (hydranencephaly) to less severe (septo-optic dysplasia).
- Correct CSP identification confirms normal central forebrain development, offering reassurance.
Conclusions:
- Accurate recognition of the CSP is vital for evaluating fetal brain development.
- The CSP serves as a critical marker for various neuroanatomic abnormalities.
- Knowledge of the CSP enhances diagnostic capabilities in obstetric sonography.

01:18Anatomy of the Brain: Ventricles
There are hollow fluid-filled cavities known as ventricles deep inside the human brain. There are two lateral ventricles, one in each cerebral hemisphere, and each has three different projections — the anterior, inferior, and posterior horns visible from the lateral side. A thin membrane called the septum pellucidum separates the two lateral ventricles. The slender third ventricle in the diencephalon is connected to each lateral ventricle via a channel called the interventricular foramen. The...
01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

01:21Cerebrospinal Fluid
Cerebrospinal fluid (CSF) is a colorless liquid that flows around the brain and the spinal cord, playing a vital role in the protection, support, and overall function of the central nervous system (CNS). CSF production, circulation, and absorption are tightly regulated processes essential for the brain and spinal cord to function properly.
CSF Production
CSF is produced mainly in the choroid plexus, a network of capillaries and ependymal cells located within the ventricular system of the brain.

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:26Cerebrum: Anatomical Overview I
The main and largest component of the human brain is the cerebrum. The cerebrum consists of two main parts: the cerebral cortex, an outer layer with wrinkles or folds known as gyri and shallow grooves called sulci, and a deeper region beneath it. The cerebrum divides into two distinct hemispheres and contains five different lobes: the frontal, parietal, temporal, occipital, and insula. The central sulcus separates the frontal and parietal lobes and two functionally important gyri — the...
