Symmetrical osteoporosis (spongy hyperostosis) in a prehistoric skull from New Mexico.

Abstract

Fragments of an Anasazi skull (Pueblo II-III) from New Mexico are described. Lesions of symmetrical osteoporosis were found and their anatomical and roentgenographic characteristics are discussed. The term symmetrical osteoporosis has led to confusion with the unrelated disease osteoporosis and should be replaced by the designation spongy hyperostosis.
