Optic tract edema in a meningioma of the tuberculum sellae

We report a case of tuberculum sellae meningioma with optic tract edema. Co ntrary to a prior report on this topic, edema along the optic tract is not only seen in craniopharyngiomas but may be seen (although rarely) in other common parasellar tumors, as in our case of a tuberculum sellae meningioma. The pathogenesis of this edema in meningioma is controversial.
