title: Sacral chondromyxoid fibroma.
abstract: A 15-year-old girl with a limp and weakness and wasting of the left leg, was found to have a large chondromyxoid fibroma of the sacrum. The lesion presented difficulties in diagnosis because of its unusual site, neurological presentation, large size and extensive extension into the soft tissues of the pelvis and buttock.
