As I read this (in the British Medical Journal) I was seized with horror at the very idea of such an alarming condition of which I had never previously heard.
Whether or not it is grammatically correct, I think (hope) I should have written, had I had a need to report on such a thing, of a baby with an asymmetrical head.
Just to make it clear that it was plagiocephaly, not polycephaly, whereof I spoke.
