Abstract:
Approximately 1% of meningiomas arise in extradural sites. Intradiploic meningiomas form only a very small proportion of this number. They tend to occur in young patients. The CT and MRI appearances, although unusual, may be characteristic of the condition. We present two cases and describe the CT and MR appearance; the latter has not previously been described.
Insights
Extradural meningiomas are rare, with intradiploic meningiomas being even rarer. These tumors typically affect young patients and may present characteristic CT and MRI findings.
Area of Science:
- Neurosurgery
- Radiology
- Oncology
Background:
- Meningiomas are tumors arising from the meninges.
- Extradural meningiomas account for approximately 1% of all meningiomas.
- Intradiploic meningiomas are an uncommon subtype of extradural meningiomas, typically found in younger individuals.
