Hyperostosis is a slow-growing benign bone tumour often seen in the bones of the cranial vault, more commonly found in elderly females. It is an incidental finding noted during radiological examination. The clinical manifestation of such tumour depends on its location inside the cranial cavity: the proximity to the paranasal sinuses, brain tissue, nerves, or blood vessels, etc. Its clinical findings may range from mild obstruction of the paranasal sinuses or blood vessels to severe compression of the surrounding cranial nerves. Here a rare case of hyperostosis of the frontal and temporal bones found during a routine cadaveric dissection in the Department of Anatomy is presented. Causes of the formation of such unusually enlarged bone masses inside the cranial cavity and their clinical presentation are discussed.
