Intradiploic meningiomas : a radiological study of two cases confirmed histologically

: 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.
