Diaphragma sellae meningiomas. Report of two cases and a review of the literature.
Diaphragma sellae meningiomas are very rare and often manifest themselves with aspecific symptoms. Before the advent of MR, the diagnosis was very difficult or even impossible. For this reason they were often included in the broader category of suprasellar meningiomas. We describe two cases of diaphragma sellae meningiomas anterior to the pituitary stalk, manifesting with visual disturbances. We present the clinic and diagnostic data and we compare our experience with that reported in the literature. The tumor were removed by pterional (case 1) and subfrontal approach (case 2) with a recover of vision. Our experience support a clear demarcation of the diaphragma sellae meningioma among the wither group of suprasellar meningiomas. It is mandatory to define its position relative to the pituitary stalk and to the diaphragma sellae to chose the best surgical approach.
