Insights

Angiostrongylus cantonensis (A. cantonensis) causes eosinophilic meningitis. A rare case of cerebral hemorrhage linked to this parasitic meningitis is presented, a complication previously undocumented in medical literature.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Parasitology

Background:

  • Angiostrongylus cantonensis (A. cantonensis) is a nematode parasite endemic to Southeast Asia, Australia, and the Pacific.
  • It is the leading cause of eosinophilic meningitis in humans.
  • Parasitic meningitis poses significant neurological risks.

Observation:

  • A case of a patient presenting with A. cantonensis meningitis was observed.
  • During the course of the illness, an intraparenchymal cerebral haemorrhage was detected.
  • This specific complication was identified during clinical assessment and diagnostic imaging.

Findings:

  • The study reports the first documented instance of intraparenchymal cerebral haemorrhage occurring secondary to A. cantonensis meningitis.
  • Diagnostic findings confirmed the co-occurrence of parasitic meningitis and intracranial bleeding.
  • The cerebral haemorrhage was directly associated with the parasitic infection.

Implications:

  • This finding expands the spectrum of known neurological complications associated with A. cantonensis infections.
  • It highlights the potential for severe vascular events in patients with eosinophilic meningitis.
  • Further research is warranted to understand the pathophysiology and management of this rare complication.

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: Pathophysiology01:29

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...

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...

Arboviral Encephalitis

Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...

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...

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...
