* '''Cerebro-venous hypertension: a frequent cause of so-called "external hydrocephalus" in infants'''{{#pmid:30474714|PMID30474714}} "External hydrocephalus (eHC) is commonly defined as a subtype of infant "{{hydrocephalus}}" consisting of macrocepahly associated with enlarged subarachnoid space and no or mild ventriculomegaly. This status is thought to be related to impaired CSF absorption because of arachnoid villi immaturity. However, other factors like the venous system might be involved in the development of the clinical picture. Seventeen patients with the typical clinical feature of eHC were included. In 15, venous sinus abnormalities were found. There was a significant correlation between the volume of the widened cortical subarachnoid space (CSAS) and the number of venous sinus segments affected. Conversely, ventricular volume was not correlated. These results support the hypothesis that impaired venous outflow plays a major role in external hydrocephalus development. Raised venous pressure increases intracranial pressure accelerating head growth, resulting in an enlargement of the cortical subarachnoid space. Increased venous pressure increases the capillary bed pressure and brain turgor preventing ventricular space to enlarge forcing displacement of ventricular CSF to the subarachnoid space. As a result, ventriculomegaly is rarely found. The descriptive term "external hydrocephalus" implying a primary etiology within the CSF system is misleading and this work supports the notion that venous hypertension is the leading cause of the clinical picture." | |||
* '''The {{Cerebrospinal fluid}} Inflammatory Response to Preterm Birth'''{{#pmid:30258368|PMID30258368}} "{{preterm birth}} is the leading risk factor for perinatal white matter injury, which can lead to motor and neuropsychiatric impairment across the life course. There is an unmet clinical need for therapeutics. White matter injury is associated with an altered inflammatory response in the brain, primarily led by microglia, and subsequent hypomyelination. However, microglia can release both damaging and trophic factors in response to injury, and a comprehensive assessment of these factors in the preterm central nervous system (CNS) has not been carried out. Method: A custom antibody array was used to assess relative levels of 50 inflammation- and myelination-associated proteins in the {{cerebrospinal fluid}} (CSF) of preterm infants in comparison to term controls. Conclusion: Preterm CSF shows a distinct neuroinflammatory profile compared to term controls, suggestive of a complex neural environment with concurrent damaging and reparative signals.

Introduction
The ventricular system develops from the single cavity formed from the hollow neural tube. This fluid-filled space is separated from the amnion following fusion of the neural tube and closure of neuropores. At different regions sites within the wall (floor of lateral ventricle and roof of the third and fourth ventricles) differentiate to form choroid plexus a modified vascular structure which will produce cerebrospinal fluid (CSF)
In development and the space within the spinal cord (central canal) and the brain (ventricles) was derived from the same space within the neural tube. In the adult these 2 spaces remain connected containing the same CSF.
Early in development the cavity within the neural tube (which will form the ventricular space) is filled with amniotic fluid. As the brain and spinal cord grow, this fluid filled space makes up the majority of the nervous system (by volume). Upon closure of the neuropores and development of the embryonic vasculature, this fluid is then synthesized by the choroid plexus, a specialized vascular epithelium. In mammals, the choroid plexuses develop at four sites in the roof of the neural tube shortly after its closure, in the order fourth (IV), lateral, and third (III) ventricles.
The choroid plexuses form one region of the blood-brain barrier that regulates the brain's internal environment.
In the adult, the choroid plexus produces about two thirds of the CSF, the rest is produced by ventricular ependymal cells and cells lining the subarachnoid space. Normal CSF contains high amounts of salts, sugars and lipids and low amounts of protein (0.3-0.7 microg/microL), though there appears to be 60+ proteins as identified by 2D gel. Presence of some protein in the CSF can be indicative of disruption of or incomplete blood/brain barrier.

Development Overview
The initial neural grove and tube, with open neuropores, is filled with amniotic fluid. By stage 13 (4 weeks, GA week 6) the neuropores are closed and the neural tube is no longer directly connected to the amniotic cavity. Initially during early 3 and 5 vesicle neural stages and prior to choroid plexus development, the "ventricular space" is reliant upon overall tube growth and directional fluid transport to maintain the fluid-filled space. There is research suggesting that hydrostatic pressure[6] and a functioning heart are required to maintain the vesicle spaces, and there are several models as to how pressure and osmotic gradients may be established. See also zebrafish model studies[7] and a recent review.[8]

Embryonic
Subarachnoid space, choroid plexus, and arachnoid villi studied in 60 normal human embryos.[10] and other studies.[11][12]
- stage 14 - primitive subarachnoid space (future subarachnoid space) cavity formation within the meninx primitiva in the areas ventral to the middle brain vesicle. Primitive subarachnoid space precedes the appearance of the choroid plexus. The primitive subarachnoid space appears earlier in the region ventral to the rhombencephalon than in the region posterior to the fourth ventricle.
- Stage 18 - dura mater is formed and spaces surround the circumference of the spinal cord, which coalesce and contain many blood vessels.
- stage 20 - primitive subarachnoid space almost completely surrounds the neural tube. Abnormal human embryo findings imply that the extra-ventricular spread of fluid of choroid plexus origin is not an essential factor for the development of the subarachnoid space.
- stage 23 - arachnoid villi do not appear even at the end of the embryonal stage. Absorption of the cerebrospinal fluid in an embryo is done by the way other than the arachnoid villi.
Fetal
Fetal Period - posterior horn of the lateral ventricle, choroid plexus of the third ventricle, suprapineal recess, interthalamic adhesion, aqueduct, and apertures in the roof of the fourth ventricle.
Anatomy
Lateral Ventricles
The paired lateral ventricles lie with the cerebral hemispheres.
Third Ventricle
The third ventricle lies midline in the diencephalon between the two thalami connecting the lateral ventricles to the cerebral aqueduct.
Cerebral Aqueduct
The cerebral aqueduct connects the third ventricle with the fourth ventricle and allows cerebrospinal fluid
Fourth Ventricle
The fourth ventricle lies within the hindbrain connected by the cerebral aqueduct to the third ventricle and with the central canal of teh spinal cord.
Central Canal
The central canal (ependymal canal) lies within the centre of the spinal cord along its length and is continuous with the brain ventricular system.
Choroid Plexus
The choroid plexus along with ventricular ependymal cells and cells lining the subarachnoid space synthesise CSF. In humans, the choroid plexuses develop at four sites in the roof of the neural tube shortly after its closure, in the order fourth (IV), lateral, and third (III) ventricles.

Human Ventricular System
A schematic diagram of structures and specialized cell types bordering the different parts of the mammalian ventricular system, and in contact with the cerebrospinal fluid (CSF)[13] Abbreviations:
|
Epithelium from the neural tube epithelium.
Mesenchyma from the meninges.
Enzymes required for CSF production are Na+/K+ ATPase and carbonic anhydrase.
CSF Synthesis
Two key enzymes are required to produce CSF they are the Na+/K+ ATPase and carbonic anhydrase.
Other known chorid plexus enzymes include: alkaline and acid phosphatases, magnesium-dependent ATPase, glucose-6-phosphatase, thiamine pyrophosphatase, adenylate cyclase, oxidoreductase, esterases, hydrolases, cathepsin D, and glutathion S-transferase. (More? Catala M., 1998)
- "The epithelial cells of the choroid plexus secrete cerebrospinal fluid (CSF), by a process that involves the movement of Na(+), Cl(-) and HCO(3)(-) from the blood to the ventricles of the brain. This creates the osmotic gradient, which drives the secretion of H(2)O. The unidirectional movement of the ions is achieved due to the polarity of the epithelium, i.e., the ion transport proteins in the blood-facing (basolateral) are different to those in the ventricular (apical) membranes."[14]
CSF Reabsorption
The main reabsorption (absorption) of CSF is thought to occur in arachnoid villi (arachnoid granulations, Pacchionian granulations, Pacchionian body), into the superior sagittal sinus, into the venous system. CSF in the subarachnoid space extends into the villi, which then project through the dura into the superior sagittal sinus.
Recently, in the rabbit model, extra-cranial reabsorption of CSF has been identified with direct venous connections between the subarachnoid space and the perispinal veins.[15] In addition, clusters of arachnoidal villi have been identified in the dorsal root of the spinal nerves and the absorptive surface areas of microvessels have been suggested to serve a putative role in reabsorption.
- Antonio Pacchioni (1665-1726) in Dissertatio Epistolaris de Glandulis Conglobatis Durae Meningis Humanae (1705) first described these arachnoid granulations.[16]
Adult CSF Normal Values
Lumbar CSF
- Opening pressure: 50–200 mm H2O CSF
- Color: Colorless
- Turbidity: Crystal clear
- Mononuclear cells: less than 5 / mm3
- Polymorphonuclear leukocytes: 0
- Total protein: 22–38 mg/dl Range 9–58 mg/dl (mean ± 2.0 SD)
- Glucose: 60–80% of blood glucose
(Data from: Clinical Methods, 3rd ed, Table 74.1)
CSF Circulation
Information below is for the adult and is based upon data from a radiologic investigation using MR imaging and radionuclide cisternography.[17]
- CSF-circulation is propelled by a pulsating flow, which causes an effective mixing. Flow is produced by the alternating pressure gradient, which is a consequence of the systolic expansion of the intracranial arteries causing expulsion of CSF into the compliant and contractable spinal subarachnoid space.
- No bulk flow is necessary to explain the transport of tracers in the subarachnoid space.
- Main absorption of the CSF is not through the Pacchionian granulations (arachnoid granulations), but a major part of the CSF transportation to the blood-stream is likely to occur via the paravascular and extracellular spaces of the central nervous system. (MH- Note this statement conflicts with previous CSF Reabsorption in literature)
- The intracranial dynamics may be regarded as the result of an interplay between the demands for space by the four components of the intracranial content (arterial blood, brain volume, venous blood and CSF).
- Interaction has a time offset within the cerebral hemispheres in a fronto-occipital direction during the cardiac cycle (the fronto-occipital "volume wave").
- Outflow from the cranial cavity to the cervical subarachnoid space (SAS) is dependent in size and timing on the intracranial arterial expansion during systole.
Abnormalities
Dandy Walker Syndrome
![](/embryology/images/thumb/a/a2/Dandy_Walker_malformation_MRI_01.jpg/300px-Dandy_Walker_malformation_MRI_01.jpg)
The vermis of the cerebellum can be small or absent, the fourth ventricle enlarges due to cyst formation.
An ultrasound study[19] of fetuses with Dandy-Walker malformation 13 to 16 weeks (GA 15-18 weeks) identified the fourth ventricle widely open posteriorly, even in the standard transcerebellar view, and the brainstem-vermis (BV) angle was > 45°, significantly increased compared to that in normal fetuses (P < 0.0001). Note that at this age, an open fourth ventricle can also found in about 10% of normal fetuses.
