Summary
Primary extradural meningiomas (PEMs) are rare tumors often managed by non-neurosurgeons. This study provides diagnostic insights and treatment guidelines for these challenging lesions, based on a large case review.
Area of Science:
- Neurosurgery
- Oncology
- Pathology
Background:
- Primary extradural meningiomas (PEMs) constitute approximately 2% of all meningiomas.
- These benign, painless masses often require management by non-neurosurgeons.
- Accurate diagnosis relies on characteristic histologic patterns and advanced imaging.
Purpose of the Study:
- To describe key features aiding in the diagnosis of PEMs.
- To present the largest published review of PEMs (n=163).
- To establish novel treatment guidelines for surgeons managing these tumors.
Main Methods:
- Comprehensive literature review of all reported PEMs.
- Analysis of collective experience from a multidisciplinary cancer center.
- Establishment of treatment guidelines based on tumor grade (WHO I, II, III).
Main Results:
- PEMs present as enlarging, painless masses.
- Surgical resection with wide margins is standard for benign (WHO I) PEMs.
- Adjuvant therapy should be considered for atypical (WHO II) or malignant (WHO III) PEMs.
Conclusions:
- PEMs require careful diagnosis and tailored treatment strategies.
- Established guidelines aim to assist surgeons unfamiliar with PEMs.
- Multidisciplinary input is crucial for optimal patient management.
