Summary

Primary malignant dural lymphoma of B-cell type is rare but treatable. Combining subtotal resection with chemotherapy offers an effective strategy for achieving remission in patients with this rare central nervous system lymphoma.

Area of Science:

  • Neurology
  • Oncology
  • Pathology

Background:

  • Primary malignant dural lymphoma of B-cell type is a rare condition.
  • Literature review indicates female predominance, immunocompetency, and longer survival in affected patients compared to intracerebral lymphomas.
  • Clinicopathological features suggest distinct classification from other central nervous system lymphomas.

Observation:

  • A 59-year-old woman presented with frontal primary malignant dural lymphoma.
  • Histological diagnosis revealed diffuse large B-cell lymphoma with a high MIB-1 index.
  • The patient underwent subtotal tumor removal followed by chemotherapy.

Findings:

  • The patient remains asymptomatic with no evidence of recurrence on MRI 30 months post-surgery.
  • A combination of subtotal resection and chemotherapy proved effective in managing this case.

  • High MIB-1 index may correlate with favorable outcomes when treated aggressively.

    • Implications:

    • Subtotal resection combined with postoperative chemotherapy represents a successful management strategy for rare malignant dural lymphomas.
    • Chemotherapy is indicated as the primary postoperative treatment following subtotal resection.
    • Further research into the distinct classification and optimal treatment protocols for dural lymphomas is warranted.
