Primary Intraosseous Meningioma in A 60-Year-Old Patient

Abstract

Introduction:
Primary intraosseous meningioma is a rare form of intra-bone tumours, and most of
the time the diagnosis is possible only after histopathologic examination. It account
for approximately 67% of extradural meningiomas.
Case report:
A 60-year-old female patient presented with a headache and a bulge at the right
fronto-parietal region. Cranial computed tomography displayed a hyperostotic lesion
that showed an enhancement after injection of contrast agent. A Right frontal craniectomy
was performed and the tumor was resected. The pathological study indicated a
primary intraosseous meningioma.
Conclusion:
Meningioma is a benign tumor that can rarely sit in the cranial bone making the
diagnosis difficult in imaging, but it can be evoked in scanner or in MRI if some
radiological signs are found. The final diagnosis is based on histology.
