Certain disorders are associated with localized or generalized cortical hyperostosis or periostitis. These include enostoses (bone islands), osteomas with or without associated Gardner’s syndrome, osteopoikilosis, osteopathia striata, melorheostosis, pachydermoperiostosis, secondary hypertrophic osteoarthropathy, vascular insufficiency, infantile cortical hyperostosis, hyperostosis frontalis interna, diffuse idiopathic skeletal hyperostosis, sternocostoclavicular hyperostosis, fluorosis, plasma cell dyscrasias, neurofibromatosis, and several rare or poorly defined syndromes. The changes must be distinguished from the periostitis that occurs as a response to an adjacent osseous process (neoplasm, infection, trauma) and from hyperostosis accompanying other congenital disorders. The candidate will learn the mechanics of putting together an electronic poster presentation in lecture type format. This will be an official peer-reviewed publication. The publication will be a favorable addition to the candidate's CV. The candidate will be the first author, and I am the second author. A candidate is not limited to completing one project. He/she can do as many as they like! (There are always topics to teach about) The candidate, myself, King's College Hospital Department of Radiology and King's College all benefit from this publication.
