The cause of this condition in terms of secondary empty sella syndrome happens when a tumor or surgery damages the gland, this is an acquired manner of the condition. [1] patients with idiopathic intracranial hypertension will have empty sella on MRI [5] The cause of primary empty sella syndrome is a congenital defect (diaphragma sellae) [6]
The empty sella sign occurs due to herniation of the subarachnoid space into the sella turcica, displacing the pituitary gland and allowing CSF to occupy the space. [3] This phenomenon is often linked to the following mechanisms: [4] Primary empty sella syndrome occurs without an underlying cause or pituitary pathology. It is associated with a ...

Neuroimaging, usually with computed tomography (CT/CAT) or magnetic resonance imaging (MRI), is used to exclude any mass lesions. In IIH these scans typically appear to be normal, although small or slit-like ventricles , dilatation and buckling [ 18 ] of the optic nerve sheaths and " empty sella sign " (flattening of the pituitary gland due to ...
Empty sella syndrome is the condition of a shrunken or flattened pituitary gland.. Since the sella turcica forms a bony caudal border for the pituitary gland, a pituitary tumor usually extends upward in the rostral direction into the suprasellar region.
Pituitary apoplexy is regarded by some as distinct from Sheehan's syndrome, where the pituitary undergoes infarction as a result of prolonged very low blood pressure, particularly when caused by bleeding after childbirth. This condition usually occurs in the absence of a tumor. [4] Others regard Sheehan's syndrome as a form of pituitary apoplexy.
