title: A case of achondroplasia with downward displacement of the brain stem.
abstract: We report a case of achondroplasia with downward displacement of the brain stem. Although upward displacement and anterior angulation deformity of the brain stem are common findings in achondroplasia, they were not observed in this case, because of a coexistent Chiari malformation.
