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 presence of a compressed ...
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 J-shaped sella sign is a radiologic sign observed on lateral views of skull radiographs as the forward elongation of the sella turcica, and its extension below the anterior clinoid process. [1] This abnormality causes the sella turcica to resemble the letter J.
Radiologic signs are the signs used for diagnosing physiological and pathological conditions in radiologic images. This list includes the names of radiologic signs in alphabetical order. This list includes the names of radiologic signs in alphabetical order.
Magnetic resonance imaging (MRI) is a medical imaging technique used in radiology to generate pictures of the anatomy and the physiological processes inside the body. MRI scanners use strong magnetic fields , magnetic field gradients, and radio waves to form images of the organs in the body.
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).
However, it may throw off MRI results so talk to your doctor before eating it if you have an MRI scheduled soon, advises the National Institutes of Health. There's also not enough evidence to say ...
The diaphragma sellae or sellar diaphragm is a small, circular sheet of dura mater forming an (incomplete) roof over the sella turcica and covering the pituitary gland lodged therein. The diaphragma sellae forms a central opening to accommodate the passage of the pituitary stalk (infundibulum) [ 1 ] which interconnects the pituitary gland and ...
