The transitional fibroblastic subtype, with lipid accumulation within the tumoral cells, is typically more aggressive and surgically challenging to resect. Case Description: A 42-year-old male presented with neck pain and progressive paresthesias in both upper extremities. Based on the radiological findings, the tentative preoperative diagnosis was lymphoma. However, the biopsy confirmed a meningioma. The patient underwent a combined extradural anterior and posterior approach, resulting in full tumor resection. Histopathologically, the final report documented a lipomatous meningioma. Conclusion: Extradural spinal lipomatous meningiomas (i.e., “en-plaque”) are rare and typically result in rapid clinical deterioration. The radiological diagnosis may be difficult, while ultrasonography helps to define their extradural location facilitating planning for gross total anterior/posterior excision where indicated.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/a656d46d-9568-48cc-9dc1-3f80fa360cc8/featured/hero-1782420868132.png","publishDate":"2019-03-26T00:00:00.000Z","doi":"10.25259/SNI-87-2019","categories":["Spine","Case Report"],"fullTextUrl":"http://surgicalneurologyint.com/wp-content/uploads/2019/03/9234/SNI-10-49.pdf"}
