Dorsal extradural meningioma: Case report and literature review

BACKGROUND: Extradural spinal mass lesions are most commonly metastatic tumors. Extradural meningiomas are rare, accounting for approximately 2.5–3.5% of spinal meningiomas; intraoperatively, they are easily mistaken for malignant tumors, especially in the en plaque variety, resulting in inadequate...

Sumario:BACKGROUND: Extradural spinal mass lesions are most commonly metastatic tumors. Extradural meningiomas are rare, accounting for approximately 2.5–3.5% of spinal meningiomas; intraoperatively, they are easily mistaken for malignant tumors, especially in the en plaque variety, resulting in inadequate surgical treatment. CASE DESCRIPTION: Our case is one of the first to describe a patient with two purely extradural meningiomas, one each between D3–D4 and between D5–D6 vertebral levels. Surgical resection was radical, and pathologically both lesions were meningothelialmeningiomas. CONCLUSIONS: Reviewing the literature, we discuss the pathogenesis, treatment strategies, and long-term behavior of these uncommon lesions.
