Neuroimaging in acute transverse myelitis

Area of Science:

• Neurology
• Inflammatory Diseases
• Diagnostic Imaging

Background:

• Transverse myelitis is an acute inflammatory condition affecting the spinal cord.
• Its diverse etiologies pose significant diagnostic challenges in clinical practice.
• Standardized approaches are needed to facilitate research and clinical management.

Purpose of the Study:

• To present an approach to the classification and work-up of transverse myelitis.
• To standardize diagnostic criteria and terminology for clinical research.
• To provide a useful tool for the clinical work-up of patients.

Main Methods:

• Categorization of transverse myelitis pathogenesis into four groups.
• Analysis of Magnetic Resonance (MR) imaging features, including cord morphology and enhancement patterns.
• Correlation of imaging findings with potential causes of transverse myelitis.

Main Results:

• Imaging appearances can be nonspecific, but specific MR features offer diagnostic clues.
• Morphology of cord involvement and enhancement patterns aid in etiological differentiation.
• Neuroimaging is crucial for identifying patient subgroups amenable to specific treatments.

Conclusions:

• A standardized classification and work-up approach is essential for transverse myelitis.
• MR imaging plays a vital role in diagnosing transverse myelitis and guiding treatment.
• Identifying specific subgroups through imaging can optimize therapeutic strategies.
