Abstract The author's eight-year-old daughter, Sarah, already suffering from a debilitating genetic muscular-skeletal disease {(Fibrodysplasia} Ossificans Progressiva or {FOP)} is diagnosed with a noncancerous brain tumor {(Craniopharyngioma).} She is taken to Children's Hospital of Philadelphia, where a neurosurgeon who specializes in treating craniopharyngiomas works, and next door to the Hospital of the University of Pennsylvania, where leading research into {FOP} is conducted. Treatment protocols for the tumor are discussed, but the final decision to do surgery is made, indirectly, by Sarah herself, when she sings her school's theme song, {“Accentuate} the Positive,” in the doctor's office.
