What is a craniopharyngioma?

The quick facts and a video link for the visual learners like myself.

• Craniopharyngioma is rare -- about 1 in million.

• Benign brain tumor but it's a real beast that likes to reoccur over time.

• Develops near the pituitary gland, a small gland at the base of the brain.

• Can affect hormone production and the endocrine system and cause a variety of symptoms, including vision problems, headaches, and hormonal imbalances.

And here's the video link that I think does a great job of explaining.
