Once pituitary tumor is detected, treatment must be taken, otherwise the tumor will grow bigger and bigger, and the continuous growth will eventually lead to various serious complications, such as vision loss, endocrine disorder, even hydrocephalus, coma and other life-threatening possibilities. Pituitary tumor is a common benign tumor in the skull. It occurs in the pituitary fossa of the pterygoid saddle area, which is benign and grows slowly but still grows continuously. The tumor may secrete a large amount of abnormal hormones, leading to symptoms of systemic endocrine disorder, infertility, decreased sexual function, hyperthyroidism and symptoms such as thick hands and feet, full moon face and buffalo back. Treatment of pituitary tumors takes the form of transnasal surgery to remove the tumor, and in the case of prolactin-type pituitary adenomas, the drug bromocriptine can also be taken for treatment.
