Another compelling reason to do something is some pituitary tumors are tiny, so tiny, sometimes we don’t even see them very well on imaging. Yet, they produce enormous amounts of a hormone. And this excess production of hormone can sometimes wreak havoc throughout the body. And so sometimes we will have a compelling reason to treat a pituitary mass even when it’s not pushing on anything. And that’s a little different twist on many brain masses where usually we’re treating because they are pushing on a critical structure. Pituitary masses form one exception to that rule where even if the masses physically small, we will sometimes treat simply because the hormone that produces produces such a untoward effect on many, many systems of the body.
