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.
Insights
This study reports a rare case of two purely extradural meningiomas, highlighting their potential misdiagnosis and discussing management strategies for these uncommon spinal tumors.
Area of Science:
- Neurosurgery
- Spinal Oncology
- Pathology
Background:
- Extradural spinal mass lesions are typically metastatic tumors.
- Extradural meningiomas are rare, comprising 2.5-3.5% of spinal meningiomas.
- En plaque extradural meningiomas can be mistaken for malignant tumors, leading to suboptimal surgical treatment.
Observation:
- A unique case involving two purely extradural meningiomas at D3-D4 and D5-D6 vertebral levels is presented.
- Both lesions were surgically resected with radical intent.
- Pathological examination confirmed both tumors as meningothelial meningiomas.
Findings:
- The case represents one of the first documented instances of dual purely extradural meningiomas.
- Radical surgical resection was achieved for both lesions.
- Histopathological analysis confirmed the diagnosis of meningothelial meningiomas.
Implications:
- This case underscores the importance of considering extradural meningiomas in the differential diagnosis of spinal masses.
- Understanding the pathogenesis and behavior of these rare tumors is crucial for effective treatment planning.
- Further literature review is needed to refine treatment strategies and predict long-term outcomes for extradural meningiomas.
