title: Benign osteopetrosis.
abstract: A case of a 3 1/2-year-old female with benign osteopetrosis is presented. There was radiographic evidence of previous fetal sclerosis of bone yielding a "bone-within-a-bone" appearance, but on radiophosphate imaging this fetal sclerosis was not hyperactive and could not be differentiated from the normal diaphysis surrounding it.
