"En plaque meningioma accounts for 2–9% of all meningiomas 5. It is 3 to 6 times more common in females with mean age of presentation 40–50 years 5."

"Due to the extensive and invasive presentation of these tumours, sometimes closer to vital structures, complete resection is usually not achievable. Partial removal can lead to a higher chance of recurrence 2. "
"There is no absolute and foolproof way of defining an en plaque meningioma from a flattish globular meningioma with an extensive dural tail (although it is important to note that the dural tail does not actually contain tumour cells). Furthermore, as en plaque meningiomas often have dramatic osseous involvement these tumours are often (erroneously) termed intraosseous meningiomas, a term which should probably be reserved for primary intraosseous meningiomas (i.e. those without intracranial extension)."
"Both CT and MR imaging are useful to evaluate the extent of extradural and calvarial involvement. These tumours commonly occur in the sphenoidal ridge, calvarium or spinal region. "
