Giant calvarial meningioma which obliterated superior sagittal sinus: Case report

37960

Interosseous meningioma, defined as meningiomas confined to the skull with no epidural or subcutaneous component, is a rarely encountered example of the primary meningiomas. It is usually a benign tumour and takes origin from arachnoids cap cells. Several etiological hypotheses have been asserted for interosseous meningiomas up to the present. The literature pointed out that the symptoms of the patients with meningiomas might vary. The findings of osteolysis and hyperostosis might also be seen by X-Ray radiograph imaging. Our case was a male and 21 years old. He admitted the polyclinics of neurosurgery with the complaint of convulsion. Intracranial component of the meningioma was measured as 90x42 mm in MRI. Imaging indicated that this was a giant calvarium meningioma which diffusely skirted along to suture lines and obliterated superior sagittal sinus in a wide area. Clinical and radiological properties of the tumour were evaluated, and the responsible mechanisms from its pathogenesis are discussed in the light of the literature.
