You could get cysts there. So there’s Rathke cleft cyst, or there’s other pituitary cysts, and those are actually fairly common, but you can easily distinguish them from tumors on an MRI scan typically. Finally you’ve got stranger tumors like craniopharyngioma yet another tumor. But with modern MRI imaging, you can usually distinguish them from the most common type of pituitary mass, which is a benign pituitary tumor. And to a large extent, we’ll probably want to focus our attention on that because the other ones are, you know, rare, have more specialized care behind them, and by and large, when people are looking for what to do with, you know, their mass, they’re usually talking about a benign pituitary tumor or a benign pituitary Adenomas.
