Molecular and Histologic Diagnosis of Central Nervous System Infections

Area of Science:

• Neurology
• Infectious Diseases
• Pathology

Background:

• Central nervous system (CNS) infections pose significant risks, leading to severe illness and death in both healthy and immunocompromised individuals.
• A broad spectrum of pathogens, including bacteria, mycobacteria, fungi, viruses, and parasites, can cause CNS infections.

Purpose of the Study:

• To highlight the diagnostic approaches for central nervous system infections.
• To emphasize the importance of integrating various laboratory techniques for accurate diagnosis.

Main Methods:

• Review of diagnostic strategies for CNS infections.
• Discussion of histologic findings, special stains, and immunohistochemistry.
• Integration of molecular testing, culture, and other laboratory results.

Main Results:

• Histologic examination with special stains and immunohistochemistry can establish a morphologic diagnosis.
• Molecular testing further classifies diagnoses identified through histology.
• Correlation of all laboratory findings is essential for accurate diagnosis and to prevent false positives.

Conclusions:

• Accurate diagnosis of CNS infections relies on a multimodal approach.
• Combining histologic, molecular, and culture data is vital for effective patient management.
• Minimizing false positives through careful result correlation improves diagnostic reliability.
