Bobby Pin

This month I'm working in pediatrics when not in my clinic.  Besides the typical time of year things like - strep, colds, stomach flu, ear infections - we occasionally do get to see some interesting things.  This came in yesterday.  Use your radiologist expertise to find the abnormality:


Hint:  14 year old girl standing in the bathroom at school, fixing her hair -  She has the bobby pin, used to keep the bangs out of her face, in her mouth. She reaches to her mouth to open the pin first, the other hand holding the stray hair in place. Suddenly the bobby pin snaps out of her hand, and shoots -  down her throat.   There you see it, sitting in her stomach.  Lucky for her, the bobby pin had plastic protective heads.  The specialist in GI matters that came to look at this film decided to just let her pass it.  Hope it comes out okay -
