Empty sella syndrome is the condition when the pituitary gland shrinks or becomes flattened, filling the sella turcica with cerebrospinal fluid instead of the normal pituitary. [2] It can be discovered as part of the diagnostic workup of pituitary disorders, or as an incidental finding when imaging the brain.
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 ...
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]
Empty sella syndrome, a bony structure that surround the pituitary gland, occurs in CSF leak patients. [46] [63] Pathophysiology. Cerebrospinal fluid is produced ...
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 increased pressure) and enlargement of Meckel's caves may be seen.
Hypopituitarism is the decreased (hypo) secretion of one or more of the eight hormones normally produced by the pituitary gland at the base of the brain. [1] [2] If there is decreased secretion of one specific pituitary hormone, the condition is known as selective hypopituitarism. [3]
