The saddle area is an anatomical structure in the brain where the pituitary gland is normally located. An occupancy in the saddle area refers to the occurrence of an occupying disease in the saddle area, usually a tumor. Benign tumors are more common in the saddle area, the most common being pituitary tumors, other meningiomas, craniopharyngiomas, and malignant ones such as gliomas. Pituitary tumors originate from the pituitary gland, and in addition to occupying lesions, they often lead to endocrine hormone abnormalities and are often diagnosed as hormone abnormalities. Meningiomas, on the other hand, are mainly manifested by compressive lesions, which may result in visual abnormalities and optic nerve damage. Gliomas are more malignant and may generally be prone to recurrence after surgery.
