What should you know about meningeal melanoma?

The meninges are protective membranes surrounding the brain and spinal cord. Melanoma in this location may begin there or may represent melanoma that has travelled from another site, so specialists need to establish the origin. Symptoms vary with the area involved and can include persistent headache, vomiting, seizures, weakness, altered sensation, balance problems, confusion, or changes in vision or speech. These symptoms have many possible causes, but a new or progressive neurological change needs medical assessment.

Diagnosis may involve neurological examination, brain or spine imaging, and laboratory analysis of tissue or fluid when appropriate. The care team may include neurology, neurosurgery, oncology, radiology, and pathology specialists. Treatment depends on the tumour’s location, extent, molecular features, symptoms, and overall health.

Arrange prompt specialist review if imaging or a clinician has raised concern about meningeal melanoma. Bring scan reports, pathology results, medication details, and a timeline of symptoms. Ask whether the team is investigating a primary meningeal tumour or spread from melanoma elsewhere, and whether additional imaging or tissue testing is needed.

Possible management may include surgery when safely feasible, radiotherapy, immunotherapy, or other systemic treatment. Surgery can sometimes obtain tissue or remove accessible tumour, but the plan must account for nearby brain and spinal structures. Follow-up imaging and examinations help the team assess response and detect change.

Seek emergency care for a seizure, sudden weakness or numbness, new difficulty speaking, severe confusion, collapse, a rapidly worsening headache, repeated vomiting, or a sudden change in vision. Do not drive yourself if neurological symptoms are severe or sudden. A known diagnosis with new symptoms also warrants urgent contact with the treating team.

Where is the tumour located, and how was it identified? Do the findings suggest a primary meningeal melanoma or spread from another melanoma? What are the goals and risks of each treatment option? How will symptoms and treatment response be monitored?
