BONE CHANGES IN THE SKULL IN DYSTROPHIA MYOTONICA

Abstract

Fourteen patients with dystrophia myotonica and a post-mortem report of another case are reported. All had radiological or other evidence of abnormalities of the skull. The most constant were a thickened calvarium, hyperostosis interna, small to very small pituitary fossa and extensive sinuses. It is believed that the high incidence of these changes cannot be coincidental and it is held that they should be accepted as some of the variable features of dystrophia myotonica.
