I put together these medical challenges. The cases are hypothetical and do not necessarily represent actual or typical presentations of medical diseases. Disclaimer is at the bottom of this page.

An 80 year old man who never sees a doctor is brought in by his children because of "weird" behavior. He has been running into doors, falling, knocking things off tables, and unable to locate anything. He says there's nothing wrong with his vision and that he's "just fine." When you show him three fingers, he says he sees two. When you do confrontation of his visual fields, it seems random which fingers he says are wiggling. When asked what color shirt his daughter is wearing, he says "red" when she is wearing a green shirt. He seems to genuinely believe what he is saying. A fundoscopic exam is shown above. An MRI makes the diagnosis.
Challenge: What's the diagnosis?
