Extra and intracranial meningiomas.

Two cases of extracranial meningiomas respectively in the left frontal region in a 64-year-old woman and in the right frontal sinus in a 13-year-old boy are reported. Both cases were associated with an intracranial meningioma later detected after primary histologic diagnosis of the extracranial surgical specimen. The possibility of an extracranial meningioma, especially when an angioblastic, fibroblastic or meningothelial pattern is prominent, must always be considered together with the existence of an intracranial equivalent, as our 2 cases clearly demonstrate.
