MRI of an unenhancing tuberculum sellae meningioma.
We present a tuberculum sellae meningioma with intrasellar extension which did not enhance with intravenous gadolinium. Identification of the diaphragma sellae, possible only on the unenhanced short TR/TE sequence, was crucial for differentiating the lesion from a pituitary adenoma, and therefore for the correct surgical approach.
