To the best of our knowledge, only a limited number of cases of melanoma brain metastases mimicking meningiomas have been reported in the literature. We describe a case of a posterior fossa dural-based melanoma metastasis and review relevant literature from the past 10 years. Case Description: A 41-year-old woman with a history of the left eye enucleation due to intraocular melanoma, without regular medical follow-up, presented with a 4-month history of localized occipital headache, followed by progressive dizziness and lower limb incoordination. Magnetic resonance imaging revealed a dural-based posterior fossa lesion at the foramen magnum with radiological features highly suggestive of a meningioma. The patient underwent complete surgical resection, and histopathological analysis confirmed metastatic melanoma. Adjuvant treatment consisted of radiotherapy and immunotherapy with ipilimumab. Conclusion: Dural-based melanoma metastases may closely mimic meningiomas both clinically and radiologically, posing a significant diagnostic challenge. Surgical management is indicated in symptomatic cases, particularly those associated with mass effect or focal neurological deficits. Adjuvant radiotherapy and immunotherapy remain important components of treatment.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/02ff6b2b-e0b4-449b-8240-77d209449b74/featured/hero-1781557440683.png","publishDate":"2026-05-29T00:00:00.000Z","doi":"10.25259/SNI_60_2026","categories":["Neuro-oncology","Case Report"],"fullTextUrl":"https://surgicalneurologyint.com/api/articles/02ff6b2b-e0b4-449b-8240-77d209449b74/pdf"}
