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 ...
In a 2002 study involving 78 patients with a migraine or tension-type headache, CT scans showed abnormalities in over a third of the patients, though arachnoid cysts only accounted for 2.6% of patients in this study. [6] A study found 18% of patients with intracranial arachnoid cysts had non-specific headaches.
For the diagnosis, brain scans (such as MRI) should be done to rule out other potential causes. Specialty: Neurology: Symptoms: Headache, vision problems, ringing in the ears with the heartbeat [1] [2] Complications: Vision loss [2] Usual onset: 20–50 years old [2] Risk factors: Hypervitaminosis A, obesity, tetracyclines [1] [2] Diagnostic method
CT scan of the brain showing a craniopharyngioma (white structure in the center of the image). This tumor may cause hypopituitarism and requires surgical removal. The diagnosis of hypopituitarism is made on blood tests. Two types of blood tests are used to confirm the presence of a hormone deficiency: basal levels, where blood samples are taken ...
U.S. President-elect Donald Trump on Saturday demanded that BRICS member countries commit to not creating a new currency or supporting another currency that would replace the United States dollar ...
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 ...
