I guess there aren't too many synonyms

Nursing the baby and Oprah came on featuring a baby born with a second head. Now this wasn't Maury. It was like Oprah suddenly changed format and became The Weekly World News. And of course since it was Oprah it was supposed to be a very empowering story about triumphing over adversity, but, oh, I don't know, maybe because Oprah said the phrase “parasitic head” 100 times in the first five minutes it took on the air of a very expensively produced freak show.

And Oprah just kept hammering that phrase: "parasitic head, parasitic head" as in "doctor, what did you feel when you first set eyes on the parasitic head?" or "did you ever, in your wildest dreams, imagine you'd give birth to a baby with a parasitic head?" Her writers could have given her some options, such as "secondary cranial appendage", "alternative face" or just called it "Claudine" for all we cared, just come up with some euphamisms so she didn't have to keep repeating "parasitic head" like she was trying to draw a croud on the midway.
