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...
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: 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...

Area of Science:

  • Neurology
  • Neurosurgery
  • Vascular Malformations

Background:

  • Extra-axial cavernous malformations (CMs) are uncommon, leading to uncertainty regarding their typical clinical progression.
  • This report details a case of a progressive CM originating from the cerebellar tentorium.

Observation:

  • A 64-year-old woman presented with diplopia, revealing a rapidly enlarging lesion on MR imaging attached to the left cerebellar tentorium.
  • The lesion eroded into the midbrain and was supplied by a branch of the middle meningeal artery.
  • Intraoperative findings confirmed a tentorial CM, which was surgically treated by coagulating the feeding artery.

Findings:

  • Initial surgical coagulation of the feeding artery was insufficient to control the tentorial CM, which recurred within 3 months.
  • Gamma knife radiosurgery was subsequently performed, leading to significant lesion shrinkage within 2 months.

Implications:

  • This case underscores the rarity and aggressive potential of tentorial cavernous malformations.
  • Gamma knife radiosurgery appears to be a highly effective treatment modality for recurrent tentorial CMs.
