HYPEROSTOSIS OF THE FRONTAL, TEMPORAL, AND SPHENOID BONES: CASE REPORT AND REVIEW OF LITERATURE

Hyperostosis of the internal table of the frontal bone is not an uncommon phenomenon. However, such hyperostosis of the temporal and/or sphenoid bone is rarely discussed in the available literature, especially in the absence of meningioma. We report a case of hyperostosis of the frontal, temporal, and sphenoid bones found during routine cadaveric dissection of an 81 year-old female. Histology revealed thickening and increased density of the lamellar bone. The periosteum was unaffected. Possible etiology is discussed.
