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 ...
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.
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]
The diagnosis is achieved with magnetic resonance imaging and blood tests. Treatment is by the timely correction of hormone deficiencies. In many cases, surgical decompression is required. Many people who have had a pituitary apoplexy develop pituitary hormone deficiencies and require long-term hormone supplementation. The first case of the ...
sella (that is, sella turcica) S: Midpoint of sella turcica: sphenoethmoidal suture: SE: the cranial suture between the sphenoid bone and the ethmoid bone: sella–nasion line: SN or S–N: Line from sella to nasion: sella–nasion–A point angle: SNA or S-N-A: Average of 82 degrees with +/- of 2 degrees sella–nasion–B point angle: SNB or ...
[48] [51] [52] MSC treatment also appears to improve the control of cerebral blood flow and blood–brain barrier permeability, [53] [54] as well as what is currently thought to be the most important mechanism of MSC treatment after stroke, the activation of endogenous neuroprotection and neurorestoration pathways by the release of cytokines ...
The signs and symptoms of hypopituitarism vary, depending on which hormones are undersecreted and on the underlying cause of the abnormality. The diagnosis of hypopituitarism is made by blood tests, but often specific scans and other investigations are needed to find the underlying cause, such as tumors of the pituitary, and the ideal treatment ...
Stroke Heroes Act FAST is a public health campaign produced by the Heart Disease and Stroke Prevention and Control Program at the Massachusetts Department of Public Health. Begun in 2006, it is dedicated to increasing stroke recognition and shortening the time between the onset of stroke symptoms and arrival at a hospital's emergency department .
