ECHO virus type 9 meningitis simulating tuberculous meningitis

Area of Science:

• Pediatrics
• Infectious Diseases
• Neurology

Background:

• Meningitis diagnosis in infants presents challenges.
• Cerebrospinal fluid (CSF) analysis is crucial for differentiating causes.
• Viral and tuberculous meningitis can exhibit overlapping CSF profiles.

Observation:

• An infant presented with specific CSF abnormalities.
• The infant's CSF showed mononuclear pleocytosis, hypoglycorrhachia, and elevated protein.
• These CSF findings are often associated with tuberculous meningitis.

Findings:

• Despite CSF findings suggestive of tuberculous meningitis, ECHO virus type 9 was isolated.
• This highlights the potential for viral pathogens to mimic tuberculous meningitis based on initial CSF parameters.

Implications:

• Early differentiation between viral and tuberculous meningitis is critical for appropriate treatment.
• Diagnostic uncertainty necessitates considering a broad range of pathogens.
• Further investigations may be required when CSF profiles are ambiguous.
