Pituitary incidentalomas are pituitary tumors that are characterized as an incidental finding. They are often discovered by computed tomography (CT) or magnetic resonance imaging (MRI), performed in the evaluation of unrelated medical conditions such as suspected head trauma , in cancer staging or in the evaluation of nonspecific symptoms such ...
A prolactinoma is a tumor of the pituitary gland that produces the hormone prolactin.It is the most common type of functioning pituitary tumor. [1] Symptoms of prolactinoma are due to abnormally high levels of prolactin in the blood (hyperprolactinemia), or due to pressure of the tumor on surrounding brain tissue and/or the optic nerves.
Pituicytoma is a rare brain tumor. It grows at the base of the brain from the pituitary gland. This tumor is thought to be derived from the parenchymal cells of the posterior lobe of the pituitary gland, called pituicytes. Some researchers [1] believe that they arise from the folliculostellate cells in the anterior lobe of the pituitary.
Pituitary gland dysfunction can occur from tumors, infections, surgeries, or for other reasons. When the pituitary gland doesn’t produce LH and FSH, there’s no signaling from the brain to the ...
Nelson's syndrome is a disorder that occurs in about one in four patients who have had both adrenal glands removed to treat Cushing's disease. [1] In patients with pre-existing adrenocorticotropic hormone ()-secreting pituitary adenomas, loss of adrenal feedback following bilateral adrenalectomy can trigger the rapid growth of the tumor, leading to visual symptoms (e.g. bitemporal hemianopsia ...
Schumer said her diagnosis was the result of steroid injections from her breast reduction and Cesarean section after her first child. Cushing syndrome is rare, affecting up to 70 out of a million ...
Many pituitary tumors (25%) are found to have areas of hemorrhagic infarction on MRI scans, but apoplexy is not said to exist unless it is accompanied by symptoms. [ 1 ] [ 4 ] In some instances, lumbar puncture may be required if there is a suspicion that the symptoms might be caused by other problems ( meningitis or subarachnoid hemorrhage ).
Inferior petrosal sinus sampling (or IPSS), is a diagnostic medical procedure used to determine whether excess adrenocorticotropic hormone (ACTH) is coming from the pituitary gland (usually a pituitary adenoma causing Cushing's disease) or from a source outside the pituitary (a rare tumor causing ectopic ACTH syndrome). The procedure is usually ...
