Pituitary adenomas are a group of abnormal cells located in the pituitary gland that grow out of control. Positive pituitary adenomas represent the presence of an adenoma examined in the saddle region of the brain, which requires a combination of symptoms and other tests to further characterize the pituitary adenomas before treatment can proceed.
Positive pituitary adenomas represent the presence of pituitary adenomas in the saddle region of the brain identified on imaging such as CT scans and MRIs, which need to be combined with symptoms and tests to further characterize the pituitary adenomas. Non-functioning adenomas can present with headaches, vision loss, and hydrocephalus due to the presence of a tumor.
If the adenoma is too large, it may compress the surrounding tissues and affect other functions. Meanwhile, if the adenoma is functional and secretes hormones on its own, it may cause gigantism, acromegaly and Cushing’s syndrome due to secretion of growth hormone, and it needs to be combined with the corresponding symptoms or 24-hour acth test to make a further diagnosis.
Positive pituitary adenomas should be treated according to the properties and size of the adenoma under the judgment of a doctor.
