Insights

Recurrent venous infarction in a child resolved as venous sinus occlusion cleared. This suggests cerebrospinal fluid (CSF) resorption in the cavum septi pellucidi and cavum vergae is pressure-gradient dependent.

Area of Science:

  • Neurology
  • Pediatric Neurology
  • Neuroimaging

Background:

  • Venous sinus occlusion can lead to neurological complications.
  • Cavum septi pellucidi (CSP) and cavum vergae (CV) are midline cerebrospinal fluid (CSF) filled spaces.
  • The role of CSP and CV in CSF dynamics is not fully understood.

Observation:

  • A 26-month-old boy presented with recurrent hemorrhagic venous infarction due to venous sinus occlusion.
  • Distension and enlargement of CSP and CV, along with hydrocephalus, were observed.
  • These abnormalities regressed concurrently with the resolution of venous occlusion.

Findings:

  • Venous hypertension secondary to sinus occlusion is hypothesized to impair CSF resorption in CSP and CV.
  • This case provides the first evidence supporting CSF resorption in the cava via a pressure gradient mechanism.
  • The pressure gradient involves septal capillaries and veins.

Implications:

  • This finding offers a novel insight into the pathophysiology of venous sinus occlusion-related neurological issues.
  • Understanding CSF dynamics in CSP and CV may aid in managing related pediatric neurological conditions.
  • Highlights the importance of venous system integrity in maintaining CSF homeostasis.

Anatomy 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...

Cranial and Spinal Meninges

The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
Cerebrospinal Fluid01:21

Cerebrospinal 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.
Increased Intracranial Pressure ll: Pathophysiology01:29

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
Cerebral Edema l: Introduction01:19

Cerebral Edema l: Introduction

Cerebral edema is a pathological increase in brain water content that disrupts intracranial pressure regulation and impairs neurological function. Because the cranial vault is rigid, even modest increases in tissue volume can compromise cerebral perfusion, distort neural structures, and initiate secondary injury. Cerebral edema develops through four principal mechanisms: vasogenic, cytotoxic, interstitial, and ionic.Vasogenic EdemaVasogenic edema arises from disruption of the blood–brain...
Cerebral Edema ll: Pathophysiology01:22

Cerebral Edema ll: Pathophysiology

Vasogenic edema is a major form of cerebral edema characterized by abnormal accumulation of fluid in the brain’s extracellular space due to disruption of the blood–brain barrier (BBB). The BBB is a specialized structure composed of endothelial cells connected by tight junctions, supported by astrocytic endfeet and a basement membrane. Under normal conditions, it tightly regulates the movement of ions, proteins, and solutes between the bloodstream and brain parenchyma. When this barrier loses...
