Cranial and Spinal Meninges01:19

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...
Increased Intracranial Pressure l: Introduction01:14

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...
Brain Abscess l: Introduction01:26

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
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 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...
Anatomy of the Brain: Ventricles01:18

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...

Summary

Multiple spinal extradural arachnoid cysts are rare in children. Surgical resection of these cysts can lead to significant improvement in neurological function.

Area of Science:

  • Pediatric Neurosurgery
  • Spinal Surgery
  • Congenital Spinal Abnormalities

Background:

  • Extradural arachnoid cysts are uncommon spinal cord compression causes in children, often linked to congenital dural defects.
  • Typically, these cysts communicate with the subarachnoid space via a dural defect.
  • While solitary cysts are documented, multiple extradural arachnoid cysts are exceptionally rare in pediatric cases.

Observation:

  • A 14-year-old boy presented with progressive lower extremity weakness, myelopathy, and severe gait ataxia.
  • Spinal magnetic resonance imaging revealed four extradural arachnoid cysts spanning from T1 to T9.
  • The patient underwent thoracic laminoplasty for en bloc resection of the cysts.

Findings:

  • Surgical excision of multiple spinal extradural arachnoid cysts resulted in immediate postoperative improvement.
  • The patient experienced enhanced motor strength and ambulation post-surgery.
  • This case highlights the successful surgical management of a rare pediatric spinal condition.

Implications:

  • Multiple spinal extradural arachnoid cysts, though rare, are treatable with surgical intervention.
  • Complete cyst resection at the spinal cord level offers a favorable prognosis for pediatric patients.
  • This case contributes to the limited literature on multiple extradural arachnoid cysts, emphasizing surgical outcomes.
