Insights

Enterovirus infections in newborns can lead to severe central nervous system disease. Neuroimaging, including cranial ultrasonography and MRI, is crucial for diagnosis and management of these neonatal enterovirus infections.

Area of Science:

  • Neonatal Neurology
  • Infectious Diseases
  • Pediatric Radiology

Background:

  • Enteroviruses are a common cause of neonatal infections.
  • Central nervous system involvement can lead to significant morbidity and mortality in neonates.
  • Early diagnosis and management are critical for improving outcomes.

Purpose of the Study:

  • To investigate the neuroimaging findings in neonatal infants with enterovirus infections.
  • To correlate imaging findings with clinical presentation and neurodevelopmental outcomes.

Main Methods:

  • Retrospective analysis of 12 neonatal infants diagnosed with enterovirus encephalitis.
  • Review of clinical data, cranial ultrasonography (cUS), and magnetic resonance imaging (MRI) findings.
  • Assessment of neurodevelopmental outcomes at 18 months follow-up.

Main Results:

  • All 12 infants showed white matter changes on neonatal MRI.
  • One preterm infant had periventricular echogenicity on cUS.
  • Outcomes varied, with 2 infants developing cerebral palsy and 10 having normal neurodevelopment.

Conclusions:

  • Enterovirus infection can result in severe central nervous system disease in neonates.
  • Neuroimaging studies (cUS and MRI) are informative for diagnosing and managing these infections.
  • Neuroimaging should be an integral part of the care for infants with enteroviruses.

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...

Encephalitis ll: Pathophysiology01:26

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...

Arboviral Encephalitis01:25

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...

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

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...

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...
