Could I have a pituitary tumor? Should I get an MRI? Is it gonna grow? Will I need an operation?
Most people with hypopituitary are not in that condition because of a pituitary tumor. I estimate that less than 5% of those with hypopituitarism are diagnosed with a pit tumor, but studies have shown over 20% of cadavers have some degree of pituitary tumor present. In my opinion anyone who’s tests show even one low pituitary hormone should get an MRI (make sure is done with and without contrast). You can’t be sure until you have one. If your doc wants you to have a CAT scan instead, then you know you are seeing the wrong doctor. In cases of pit tumor is present I recommend one see an endo who specializes in pituitary tumors. In half the cases, pit tumors don’t grow to large and will stop growing. Any pituitary tumor should be monitored by MRI at least once a year. In the vast majority of cases, an operation is not necessary, but is necessary when the tumor pushes on the optic nerve or pushes against the hypothalamus or sinus cavity.
