Insights
This article discusses how pediatric central nervous system infections evolve with country development, emphasizing neuroimaging roles. It covers congenital infections, neonatal diseases, and long-term effects, showcasing diverse imaging findings.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Radiology
Background:
- Pediatric central nervous system (CNS) infections present differently as countries develop.
- Understanding evolving neuroimaging findings is crucial for diagnosis and management.
- Congenital and neonatal infections remain significant challenges.
Purpose of the Study:
- To highlight the changing landscape of pediatric CNS infections.
- To review the utility of various neuroimaging modalities in pediatric CNS infections.
- To discuss common and emerging infectious etiologies and their imaging features.
Main Methods:
- Review of neuroimaging findings in pediatric CNS infections.
- Discussion of congenital infections (TORCH), neonatal infections (Group B Strep, E. coli), and outbreaks.
- Inclusion of iatrogenic, opportunistic, immune-mediated changes, and mimics.
Main Results:
- Neuroimaging, particularly cranial ultrasound and MR imaging, plays a vital role.
- Common findings include congenital TORCH infections, neonatal bacterial meningitis, and viral encephalitis.
- Long-term sequelae and non-infectious mimics require careful consideration.
Conclusions:
- The profile of pediatric CNS infections is dynamic and influenced by socioeconomic factors.
- Comprehensive neuroimaging interpretation is essential for accurate diagnosis and patient care.
- Awareness of diverse etiologies, including congenital, neonatal, and opportunistic infections, is critical.
Abstract:
This article highlights the changing profile of the pediatric patient with central nervous system infection as countries develop and the roles of different imaging modalities such as cranial ultrasound, MR imaging, and computed tomography. It discusses the commonly encountered congenital toxoplasmosis, rubella, cytomegalovirus, herpes simplex (TORCH) infections, Group B Streptococcal and Escherichia coli infections in the neonatal period, and disease outbreaks affecting children. Iatrogenic, opportunistic, and immune-mediated changes as well as long-term effects of infection and mimics of infection are also discussed. Variety of images is provided to show the range of neuroimaging findings encountered, particularly on cranial ultrasound and MR imaging.
