Summary
Diagnosing rare pseudotumoral multiple sclerosis (MS) can be challenging. Stereotactic brain biopsy is essential for confirming MS and ruling out tumors or infections in these atypical cases.
Area of Science:
- Neurology
- Pathology
- Radiology
Background:
- Multiple sclerosis (MS) is typically diagnosed using clinical, biological, and imaging data.
- Rare pseudotumoral MS cases present with atypical features mimicking neoplastic or infectious conditions.
Observation:
- A 28-year-old man presented with acute right hemiparesis.
- Brain MRI revealed a left frontoparietal mass with edema, suggesting a tumor or infection.
- Stereotactic biopsy was performed for definitive diagnosis.
Findings:
- Pathology showed white matter disorganization with foamy macrophages and lymphocytes, indicative of demyelination.
- The patient experienced a relapse after initial improvement with corticosteroid therapy.
- Follow-up MRI demonstrated significant lesion size reduction.
Implications:
- Stereotactic brain biopsy is crucial for diagnosing rare pseudotumoral MS.
- This procedure helps differentiate MS from neoplastic and infectious mimics.
- Accurate diagnosis guides appropriate treatment and management strategies for complex MS presentations.
