You must have some special mod on if it's doing that. As Kora said above, it can only be obtained with console commands. Alternatively if you have the Unofficial Dawnguard Patch, the crown gets added to Vyrthur's armour set and when you have defeated him, you can loot the crown off him. There was some other strange glitch that someone showed on Youtube but it's very difficult and involved scaling a cliff, though I think others tried to replicate the glitch and didn't succeed, leading many to think it was made-up, but that's the only other alternative I can think of.
