Diffuse pleural metastasis from atypical meningioma.

Area of Science:

• Neuro-oncology
• Thoracic Oncology

Background:

• Meningioma is the most common primary brain tumor, typically benign.
• Metastasis from meningioma is exceptionally rare, with no usual metastatic potential.

Observation:

• A 69-year-old male with a history of meningioma presented with respiratory symptoms.
• Imaging revealed diffuse pleural metastasis, 10 years post-surgical management of recurrent meningioma.

Findings:

• The case highlights a rare instance of meningioma metastasis to the pleura.
• This underscores the importance of considering metastatic disease in patients with a history of meningioma, even years later.

Implications:

• This case provides valuable insights into the clinical presentation, diagnostic workup, and management strategies for metastatic meningioma.
• It emphasizes the need for long-term surveillance in meningioma patients due to the potential for late metastasis.
