What Are the Different Types of Pituitary Tumor?
A pituitary tumor, or pituitary adenoma, is a solid mass of abnormally growing cells located in the pituitary gland, which is found at the lower part of the brain. Their sizes are usually in the smaller ranges, so pituitary tumors are difficult to detect and thus can continue to be undiagnosed until critical symptoms surface. The pituitary gland is technically not part of the brain and has a different composition from the brain tissues, so pituitary tumors are not considered to be brain tumors. The different types of pituitary tumors can be classified into various groupings, such as microadenomas or macroadenomas and functioning tumors or non-functioning tumors. They include adrenocorticotrophic tumors, gonadotrophic tumors, lactotrophic tumors, somatotrophic tumors and thyrotrophic tumors.
