Macrocephaly and sclerosis of the tubular bones in an isolated patient: a mild case of craniodiaphyseal dysplasia?
We report a 56-year-old woman, mainly suffering from painful legs and the inability to run. Radiologically, marked sclerosis and hyperostosis of the skull bones is present resulting in macrocephaly. Most tubular bones of the limbs, as well as the clavicles, are affected by sclerosis. By mutation analysis of the TGFB1, SOST and LRP5 genes, we were able to exclude the diagnoses of Camurati-Engelmann disease, Van Buchem disease, sclerosteosis, high-bone-mass trait and endosteal hyperostosis (Worth type). We believe this patient represents one of the very few examples of adult craniodiaphyseal dysplasia with a mild form of the disease and moderate facial changes.
