ABSTRACT
BACKGROUND: Extradural spinal meningiomas are rare, and few appear as lipomatous meningiomas in an "en-plaque" form. 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.
