Summary
Dural plasmacytoma, a rare condition, can indicate underlying immunoglobulin (Ig) G-kappa multiple myeloma (MM). Early diagnosis and systemic evaluation are crucial for differentiating it from solitary dural plasmacytoma due to vastly different prognoses.
Area of Science:
- Neurology
- Oncology
- Pathology
Background:
- Multiple myeloma (MM) rarely involves the dura mater.
- Dural plasmacytoma is an uncommon manifestation of plasma cell disorders.
Observation:
- A 72-year-old woman presented with headaches and hemiparesis.
- MRI revealed a right frontal extraaxial dural lesion.
- Biological studies showed hypercalcemia, hyperproteinemia, and a serum gamma globulin peak.
Findings:
- Microscopic and immunohistochemical analysis confirmed IgG-kappa MM.
- The patient had a poor prognosis, dying 3 years after symptom onset despite treatment.
- This case highlights the importance of differentiating myelomatous dural involvement from solitary dural plasmacytoma.
Implications:
- Dural plasmacytoma necessitates a thorough systemic evaluation for multiple myeloma.
- Distinguishing between myelomatous and solitary dural plasmacytoma is critical for patient management and prognosis.
- Aggressive systemic disease significantly impacts survival in cases of dural plasmacytoma.
