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 surgical treatment.


METHODS
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.
