Freak Show

 

    Di at Doctor and Covenants pointed me to this story, where a brain surgeon was operating to remove a mass from a patient and and ended up finding a foot.  The story states that this is either a rare type of tumor called a teratoma or is it a rare case of a twin that remained attached to the patients and was totally enveloped into the skull, a condition called fetus in fetu.

         The image is striking, and gives a certain visceral reaction, which is largely why pictures like this make their rounds on the internet.
