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.
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 ...
The failure to breastfeed and amenorrhea no more periods, were seen as the syndrome (a collection of symptoms), but we now view Sheehan's as the pituitary failing to secrete 1-5 of the 9 hormones that it normally produces (the anterior (front) lobe of the pituitary produces FSH, LH, prolactin, ACTH (Adreno-cortico-trophic hormone),TSH (Thyroid ...
"Idiopathic" means of unknown cause. Therefore, IIH can only be diagnosed if there is no alternative explanation for the symptoms. Intracranial pressure may be increased due to medications such as high-dose vitamin A derivatives (e.g., isotretinoin for acne), [10] long-term tetracycline antibiotics (for a variety of skin conditions).

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.

Cervicocranial syndrome or (craniocervical junction syndrome, CCJ syndrome) is a combination of symptoms that are caused by an abnormality in the cervical vertebrae leading to improper function of cervical spinal nerves. Cervicocranial syndrome is either congenital [1] or acquired. [2]
