The diaphragma sellae or sellar diaphragm is a small, circular sheet of dura mater forming an (incomplete) roof over the sella turcica and covering the pituitary gland lodged therein. The diaphragma sellae forms a central opening to accommodate the passage of the pituitary stalk (infundibulum) which interconnects the pituitary gland and the hypothalamus.
The diaphragma sellae is an important neurosurgical landmark.
