The impact of pituicytoma on hormone secretary function

Pituicytoma had a negative endocrine secretory function in this study. However, pituicytoma was associated with hyperactivity of the surrounding pituitary glandular tissue, which resulted in clinically abnormal hormone secretion. The diagnosis of pituicytoma before a thorough pathological examination is difficult when the patients present with hormone dysfunction. Therefore, maximum resection of the pituitary tumor is necessary to make the diagnosis of pituicytoma and to exclude pituitary adenoma.
