The easiest way for it to grow is up because up there no bone that direction. The pituitary sits in this little cup almost. It’s got a fancy word that’s associated with it called the Sella Turcica, which means Turkish saddle. But suffice it to say that it sort of sits in a cup of bone. And so the easiest way for it to grow is up. And if you were sitting in the pituitary and you look straight up, what you’d see is the two optic nerves on top of you forming an x. They come together and form a structure called the chiasm. But the bottom line is the both optic nerves, which are sending signals from your eye and ultimately to your brain, sit on top of the pituitary. So as this tumor grows, that’s the first structure it’s gonna touch and then distort.
