CT scan of the brain showing a craniopharyngioma (white structure in the center of the image). This tumor may cause hypopituitarism and requires surgical removal. The diagnosis of hypopituitarism is made on blood tests. Two types of blood tests are used to confirm the presence of a hormone deficiency: basal levels, where blood samples are taken ...
