Pituitary tumors can be life-threatening, especially relatively large pituitary tumors and pituitary tumors of an obvious endocrine function nature, and pituitary tumors of a recurrent nature. Firstly, huge pituitary tumors can affect the pituitary gland and compress the optic nerve and even other brain tissues such as hypothalamus, causing a series of uncomfortable symptoms such as headache, nausea, vomiting, numbness and weakness of limbs, speech dysfunction, etc. In some patients, the compression is so severe that urinary collapse and electrolyte disorders can occur. Secondly, endocrine pituitary tumors secrete various hormones, causing imbalance in body homeostasis and regulation. Finally, recurrent pituitary tumors, which are often malignant in growth, can erode bone, cause various cerebrospinal fluid leaks, and form intracranial infections, which can also lead to the death of the patient. Therefore, if a pituitary tumor is present, it must be treated aggressively and relevantly.
