From News of the Weird:
In April, the Mayo Clinic in Scottsdale, Ariz., surgically removed a dead worm from the brain of a woman because, having entered the woman’s body via pork she ate in Mexico and then having died, its carcass was causing her periodic seizures. The operation took six hours and required that the patient be only mildly sedated, in that she needed to keep talking to surgeons to help guide them from point to point in her brain.
