Insights

Chronic active Epstein Barr virus (EBV) infection can cause severe neurological issues, including meningitis and vasculopathy. This case highlights a rare presentation in an 11-year-old boy with arterial aneurysms and bone marrow aplasia.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Pediatrics

Background:

  • Chronic active Epstein Barr virus (EBV) infection presents with diverse manifestations affecting the central nervous system.
  • Neurological complications of EBV can involve meningeal, parenchymal, and vascular structures.

Observation:

  • An 11-year-old boy experienced 18 months of headache, fever, and seizures.
  • Brain MRI revealed fusiform aneurysmal dilatations in both anterior and posterior cerebral circulation.
  • Cerebrospinal fluid analysis showed lymphocytic pleocytosis, elevated proteins, low sugar, and positive EBV PCR.

Findings:

  • The patient was diagnosed with chronic lymphocytic meningitis and central nervous system vasculopathy.
  • He later developed pancytopenia due to bone marrow aplasia, likely linked to EBV-associated X-linked lymphoproliferative disorder.
  • The vasculopathy presented as diffuse fusiform aneurysmal dilatation, a rare but documented complication of chronic EBV.

Implications:

  • This case underscores the rare but severe neurological and hematological complications of chronic active EBV infection.
  • Highlights the importance of considering EBV in pediatric cases of unexplained meningitis, vasculopathy, and bone marrow failure.
  • Emphasizes the need for further research into the pathogenesis and management of EBV-related vasculopathy and lymphoproliferative disorders.

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...

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...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
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...

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...
