Pituitary tumor diameter refers not necessarily to the upper and lower length, but the length of the longest diameter of the tumor.
Pituitary tumor is a group of neoplastic diseases from the adenopituitary gland, neuropituitary gland and embryonic craniopharyngiocystic remnant squamous epithelium, is a common intracranial tumor, clinically for the size of pituitary tumors based on the diameter, where the diameter does not have a fixed direction, refers to the longest diameter of the pituitary tumor.
According to the diameter of pituitary tumors, they can be divided into microadenomas and macroadenomas, with the diameter of the former being <10mm and that of the latter being ≥10mm.
Microadenomas without functional pituitary tumors have no obvious clinical symptoms, whereas macroadenomas may cause headaches and visual field defects due to the compression of the surrounding tissues, and functional pituitary tumors, regardless of their size, may present with hormone secretion abnormality syndromes.
When pituitary tumor occurs, it is necessary to actively seek medical treatment, improve the measurement of relevant hormone levels, and according to the actual condition of the doctor to formulate a reasonable treatment plan.
