Olfactory groove meningioma

Discussion:

Meningiomas are common.   They may be multiple and a wide range of potential imaging appearances are possible.  However, the vast majority have a typical appearance, as in this case with avid homogenous enhancement and a dural tail.

A small proportion occur along the olfactory groove/planum sphenoidale with a very central, symmetrical appearance.

Surgery was performed which confirmed two meningiomas.
