Abstract

Insights

A rare case of a benign sphenoid wing meningioma presenting as a sudden intracerebral hemorrhage is described. Prompt surgical removal led to excellent patient recovery without lasting neurological deficits.

Area of Science:

  • Neurosurgery
  • Neuropathology
  • Neuroradiology

Background:

  • Meningiomas, particularly sphenoid wing meningiomas, are typically slow-growing benign tumors.
  • Intracerebral hemorrhage is an uncommon presentation for meningiomas, especially in the absence of predisposing factors.

Observation:

  • A 68-year-old female presented with sudden coma due to intracerebral hemorrhage.
  • Computed tomography (CT) and CT angiography revealed hemorrhage but no vascular anomaly.
  • Intraoperative findings identified a lateral sphenoid wing meningioma with intratumoral bleeding extending into the brain parenchyma.

Findings:

  • The patient underwent simultaneous hematoma evacuation and complete tumor resection.
  • Histopathological analysis confirmed a World Health Organization (WHO) grade I meningothelial meningioma.
  • The patient experienced a favorable recovery with no significant neurological sequelae.

Implications:

  • This case highlights an extremely rare presentation of a benign sphenoid wing meningioma.
  • It underscores the importance of considering uncommon etiologies for intracerebral hemorrhage.
  • The study discusses potential mechanisms for intratumoral bleeding in meningiomas.

Hemorrhagic Stroke l: Introduction01:17

Hemorrhagic Stroke l: Introduction

A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Hemorrhagic Stroke ll: Pathophysiology

A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Bacterial Meningitis I: Introduction01:22

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
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,...
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...
