There is an extra-axial mass along the planum sphenoidale/olfactory groove within the midline with an intermediate signal intensity on T1-weighted sequences and slightly high signal intensity on T2-weighted sequences and measures approximately 2.3 x 2.0 x 1.4 cm. There are areas of susceptibility artifact within the mass consistent with areas of calcification. There is no restricted diffusion. There is homogeneous enhancement with an enhancing dural tail. There is mild mass effect on adjacent brain parenchyma. There is no associated vasogenic edema. The mass does no appear to involve the optic chiasm or invade the paranasal sinuses.
