Neuroimaging of meningeal disease
1Department of Radiology, Emory University School of Medicine, Atlanta, GA.
Abstract:
In the past two decades, the advent of CT and MRI has made a considerable impact on the evaluation of meningeal diseases, conditions once regulated to cytological, histopathological, or postmortem analyses alone. This article reviews the imaging findings in various meningeal processes with particular attention to the anatomic definition of the meningeal layers and their relationship to the development of meningeal pathology and consequent imaging characteristics.
Insights
Computed tomography (CT) and magnetic resonance imaging (MRI) have revolutionized the diagnosis of meningeal diseases. This review details imaging findings related to meningeal anatomy and pathology.
Area of Science:
- Neurology
- Radiology
- Pathology
Background:
- Meningeal disease diagnosis historically relied on invasive or postmortem methods.
- Recent advancements in CT and MRI have transformed diagnostic capabilities.
- Understanding meningeal anatomy is crucial for interpreting pathology.
Purpose of the Study:
- To review imaging findings in various meningeal diseases.
- To emphasize the relationship between meningeal layer anatomy and disease presentation.
- To correlate imaging characteristics with specific meningeal pathologies.
Main Methods:
- Review of imaging findings from CT and MRI studies.
- Correlation of imaging findings with known meningeal anatomy.
- Analysis of pathological processes affecting the meninges.
Main Results:
- CT and MRI provide detailed visualization of meningeal layers.
- Specific imaging patterns are associated with diverse meningeal pathologies.
- Anatomical understanding enhances diagnostic accuracy.
Conclusions:
- CT and MRI are indispensable tools for evaluating meningeal diseases.
- Detailed knowledge of meningeal anatomy improves the interpretation of imaging findings.
- Imaging offers a non-invasive window into meningeal pathology.
