An Indiana woman undergoing surgery in Los Angeles to remove a tumor experienced a twist worthy of a sci-fi plot when doctors discovered an embryonic twin in her brain. Yamini Karanam, 26, was unaware of what was happening in her head until she underwent a procedure designed to reach deep into the brain to extract the tumor. After waking up from the surgery, Karanam was surprised to learn of the "teratoma" -- her embryonic twin, a rarity in modern medicine, complete with bone, hair and teeth.
