Figure 21. Sagittal (B) enhanced T1 weighted image. There is a suprasellar meningioma which appears to be arising from the planum sphenoidale and is seen extending along the floor of the anterior cranial fossa where a dural tail (arrow) is visible. The pituitary gland itself appears normal and a cleft of CSF is visible between the meningioma and the pituitary tissue. The meningioma is displacing and possibly involving the optic nerves anterior to the chiasm.
