Sellar tumor意思

"Sellar tumor" is a term used to describe a tumor that originates in the sella turcica, which is a bony structure in the brain located at the base of the skull. The sella turcica houses the pituitary gland, which is often referred to as the "master gland" because it produces hormones that regulate various bodily functions, including growth, metabolism, and reproductive functions.

Sellar tumors can be either benign (non-cancerous) or malignant (cancerous) and may arise from the pituitary gland itself (pituitary adenomas) or from other cells within the sella turcica. They can also spread to the sella turcica from other parts of the brain or body.

Symptoms of a sellar tumor can vary depending on the size and type of the tumor, but they may include headaches, vision problems, changes in hormone levels (which can lead to symptoms such as weight gain or loss, changes in menstrual cycle, impotence, and others), and neurological deficits.

Diagnosis of a sellar tumor typically involves imaging tests such as MRI or CT scans, as well as hormone tests to assess the function of the pituitary gland. Treatment options may include surgery to remove the tumor, radiation therapy, and/or medications to control hormone production.
