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]
Empty sella in MR imaging. The empty sella sign is a radiological finding characterized by the partial or complete filling of the sella turcica with cerebrospinal fluid (CSF), causing the pituitary gland to appear flattened or compressed against the walls of the sella. [1] This results in the sella appearing "empty" on imaging, despite the ...
[6] [7] This procedure allows the surgeon to access the sellar space, or sella turcica. The sella is a cradle where the pituitary gland sits. Under normal circumstances, a surgeon would use this approach on a patient with a pituitary adenoma. The surgeon starts with the transnasal approach prior to using the transsphenoidal approach.
Sheehan's syndrome, also known as postpartum pituitary gland necrosis, occurs when the pituitary gland is damaged due to significant blood loss and hypovolemic shock (ischemic necrosis) or stroke, originally described during or after childbirth leading to decreased functioning of the pituitary gland (hypopituitarism). [1]
In larger case series, the mortality was 1.6% overall. In the group of patients who were unwell enough to require surgery, the mortality was 1.9%, with no deaths in those who could be treated conservatively. [8] After an episode of pituitary apoplexy, 80% of people develop hypopituitarism and require some form of hormone replacement therapy.

Patients with extra-renal salt losses complicated by hyponatremia were found to be common-place, and consistent with McCance's description, they excreted urine virtually free of sodium. [22] In 1950, Sims et al, published their work that suggest observed relation between hyponatremia and pulmonary tuberculosis.
