Meningioma is a type of tumor that commonly occurs in the central nervous system (CNS). Hyperostosis can occur in meningiomas. Hyperostosis is a condition in which the bone surrounding a meningioma thickens abnormally. Although hyperostosis is usually benign, leaving a small portion of bone that still has hyperostosis can increase the risk of recurrence. The case report was carried out by reviewing 3 medical records of meningioma sufferers with hyperostosis.
