Actually I had a medical student make the same assumption about a patient who had "anisocoria" (the medical term for this). The key thing is that an intracerebral hemorrhage produces this as a LATE finding. IN other words, if it were an intracerebral hemorrhage causing this he would most likely NOT be walking and talking. Figuring out what it IS would be impossible over the internet. Here is a reliable website that discusses other possibilities (unfortunately technical).
Feel free to ask a follow-up question.
You are welcome.
