Insights

A small meningioma caused a stroke in a young man, presenting with transient ischemic attacks. This rare case highlights the importance of considering meningiomas, even small ones, as a cause of cerebral infarction.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Meningiomas are typically benign tumors arising from the meninges.
  • Cerebral infarction, or stroke, is a serious condition resulting from interrupted blood supply to the brain.
  • Small meningiomas are rarely associated with cerebrovascular events.

Observation:

  • A 31-year-old man experienced transient ischemic attacks (TIAs) followed by persistent left lower limb weakness.
  • MRI revealed an acute cerebral infarction in the right frontal lobe and a 20 mm planum sphenoidale meningioma encasing the right anterior cerebral artery.
  • Cerebral angiography confirmed occlusion of the right A(2) segment.

Findings:

  • Surgical removal of the meningioma was successful (gross total removal).
  • Histological examination confirmed a meningothelial meningioma.
  • This case represents an extremely rare instance of a small meningioma causing significant cerebrovascular compromise.

Implications:

  • The findings underscore the need to consider meningiomas, irrespective of size, in the differential diagnosis of cerebral infarction, particularly in younger patients.
  • Early recognition and surgical intervention are crucial for managing meningioma-induced stroke.
  • This case contributes to the understanding of rare meningioma complications and their management.

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...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
Bacterial Meningitis II: Pathophysiology01:26

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...
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...
Viral Meningitis01:18

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
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,...
