One of ours did something similar last year. He ended up dying from an abscess that accumulated under the skull from the damage he did to his head between his pedicles, it was pushing on his brain, and caused "goat polio" (thiamine def). We treated him once and he rebounded. 3 weeks later he relapsed, and died. When we caped him out, we found the mass that had seeped in through a pencil size hole that we couldn't see because of the crazy base growth. His bases were seperate, but only by a hair.
