Multiple intracranial Meningiomas

A19 yo male with history of mild headache.

MRI study shows:
Three meningiomas, largest is falcine meningioma along inter hemispheric fissure, 2nd in left frontal region near orbit, 3rd smaller one in left parietal region.  Signal iso intense to cortical grey matter. Mild perilesional odema.
No vestibular schwannoma on any side.
Clinically no family history or signs of NF2. No family history of meningiomatosis.

Imaging diagnosis : Multiple intracranial meningiomas.

Multiple intracranial meningiomas is a condition where more than one meningioma in several intracranial locations in the same patient without signs of neurofibromatosis.
Incidence varies from 1 to10%.

Multiple intracranial meningiomas do not imply neurofibromatosis.
Despite of multiplicity, multiple meningiomas does not differ in prognosis from benign solitary meningiomas.
