How can pituitary tumors be detected early? It should be taken seriously after the appearance of related symptoms, such as a CT examination, and then after a more detailed MRI examination, it can be clarified. Generally speaking, if the endocrine changes are not effective after treatment, or if there is headache, visual impairment, or any of the endocrine should be considered, and if they occur at the same time, they should be promptly checked. Pituitary tumors are usually found in women aged 20-40 years old, because women have more hormonal changes and fluctuations during their lifetime. 1.Endocrinological examination The application of endocrine radioimmuno-ultra-microscopic method to directly measure growth hormone, prolactin, adrenocorticotropic hormone, thyroid-stimulating hormone, melanin-stimulating hormone, follicle-stimulating hormone and luteinizing hormone of pituitary gland is very helpful for the early diagnosis of pituitary adenoma. 2.Radiological examination (1)Pterygoid saddle image: It is one of the basic examinations. When the pituitary adenoma is small, there can be no change in the saddle, but as the tumor grows, it can lead to the enlargement of the saddle, bone destruction and saddle back erosion. (2) CT scan: After enhancement with intravenous contrast, it can show pituitary adenoma of 5mm in size. Smaller tumors are still difficult to show.
