Abstract: A retrospective analysis was carried out in 220 cases of nonfunctional pituitary adenoma (NFA).The diagnosis was based on negative immunohistochemical staining,no elevation of plasma hormone level,and no symptom caused by increased hormone level.Incidence of NFA was the highest(33.13％) among the pituitary tumors.It was more common in males than in females (132 ∶ 88).The highest prevalence resided in the elder group.N FA often caused pituitary apoplexy,and mainly presented as compression symptoms including visual field abnormalities (85.00％),headache (80％),hypopsia (68.66％),and other symptoms of hypopituitarism (44.04％).Imaging features showed tumor size usually within 2-4 cm (71.82％),and aggregated degree Ⅲ or Ⅳ (83.64％).
