I probably did not need to add the NSFW mark though I did, just in case.

(sorry if this has already been posted recently or if anything is wrong) Pediatric neurosurgeon Dr. Paul Grabb was astonished to discover a tiny foot growing inside the brain of three-day-old Sam Esquibel. It was initially thought to be either a teratoma (a congenital brain tumor composed of foreign tissue such as muscle, hair, or teeth) or a fetus-in-fetus, a developmental anomaly in which one fetal twin begins to form inside the other. Teratomas are rare congenital brain tumors, but finding one in such a complex shape (a foot) was unprecedented. The foot was discovered and surgically removed in 2008. The procedure was a success, and it was treated like any other teratoma.
