Definition

A pituitary mass is an abnormal growth of cells affecting the pituitary gland. The pituitary gland or hypophysis controls a series of hormones that regulate growth, metabolism, and stress. Most pituitary masses or tumors are benign and are not associated with metastatic involvement. However, a pituitary mass can cause excessive hormone production, resulting in an extensive array of symptoms corresponding to the affected hormone. The presenting symptoms are also related to the lesion’s growth and size, which may include headaches, visual deficits, nausea, and vomiting. Pituitary masses can also produce prominent hormonal conditions, such as Cushing’s disease and acromegaly.
