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 ...
The sella turcica is located in the sphenoid bone behind the chiasmatic groove and the tuberculum sellae.It belongs to the middle cranial fossa. [1]The sella turcica's most inferior portion is known as the hypophyseal fossa (the "seat of the saddle"), and contains the pituitary gland (hypophysis).
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]

[14] [5] Some possible predisposing factors to Sheehan's syndrome may include: disseminated blood coagulation (DIC), hypotension, small sella turcica size, and blood clots from a pre-existing hypercoagulable disorder. [9] Atony of the uterus is a leading cause of post-partum hemorrhage, therefore uterine atony could induce Sheehan's syndrome. [15]
The pituitary gland is located in a recess in the skull base known as the sella turcica ("Turkish saddle", after its shape). It is attached to the hypothalamus, a part of the brain, by a stalk that also contains the blood vessels that supply the gland. It is unclear why pituitary tumors are five times more likely to bleed than other tumors in ...
The tuberculum sellae (or the tubercle of the sella turcica) is a slight [1] median elevation upon the superior aspect of the body of sphenoid bone (that forms the floor of the middle cranial fossa [2]: 508-509 ) at the anterior boundary of the sella turcica (hypophyseal (pituitary) fossa) [2]: 509 and posterior boundary of the chiasmatic groove.
