“…The symptomatic cases of intraosseous meningioma should be surgically treated by excising the tumor and by reconstructing the bones as required [3]. In the present case, however, we could not attempt the surgical removal of meningioma and osteoplasty since the meningioma was widely spread across the sagittal sinus in the parieto-occipital skull.…”

“…1D). Among 39 reported cases of intraosseous meningioima, the most common site of involvement is the orbit followed by the fronto-parietal region and anterior cranial fossa [1][2][3]. Hyperosteosis is the most common radiographic abnormality, and is found in 60% of the cases.…”

“…However, in our case, tumour behaves extending along the coronal suture line by following the sagittal suture. Crawford et al (1995) reported that there was no direct relationship between interosseous meningiomas and trauma. In a different approach of Shuangshoti et al (1971) reported that because multipotential mesenchyme cells are able to differentiate into different tissues, Meningiomas may arise from these mesenchyme precursors.…”

ÖZETKalvaryuma yerleşen interosse meningiomalar primer meningiomaların nadir bir örneğidir. Genellikle benign tümörlerdir ve araknoid kep hücrelerinden köken alırlar. Etyolojide çeşitli hipotezler öne sürülmüştür. Direk röntgen grafilerinde hiperosteosis ve osteolizis görülebilir. Meningiomalı hastaların semptomları değişkendir. Bizim olgumuz 21 yaşında erkek hasta, konvülziyon şikayetiyle başvuruyor. MRI da intrakranial komponenti de olan 90x42 mm olan diffuz olarak sütür hatları boyunca uzanan çok geniş bir alanda kafatası kemiklerini tutan ve superior sagittal sinüsü invaze eden dev bir kalvaryal meningioma olgusunun klinik, radyolojik özelliklerini değerlendirdik ve patogenezden sorumlu mekanizmaları literatür ışığında tartıştık.J. Exp. Clin. Med., 2012; 29: 225-228 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.

“…[25] Rarely PIMs may present as an osteolytic skull lesion. [18,22] The osteoblastic subtype may be mimicked by other entities that appear as a focal hyperdense lesion on CT, including meningioma "en plaque", osteoma, osteosarcoma, Paget disease, and fibrous dysplasia. [15,21] Clinical informations and radiologic details can further guide the differential diagnosis.…”

We illustrate a case of a giant primary intraosseous meningiomas (PIMs) with optic nerve compression treated by partial resection. A 48-year-old female presented with visual disturbances exophthalmus, diplopia and eye pain due to optic nerve compression. The patient had a past history of fibrous dysplasia treated surgically with partial resection by ENT in 2010. Histology confirmed the diagnosis. Two years later she presented with further decrease in visual acuity and diffuse hyperostosis. In this context she underwent a neurosurgical procedure consisting in craniotomy and further partial resection of the lesion including optic canal decompression. The second pathological examination demonstrated an extensive meningioma (WHO grade I) of the skull base.We recommend that in cases of diffuse hyperostosis the differential diagnosis include diffuse intraosseous meningioma. If complete surgical resection is not achievable, a biopsy to confirm the diagnosis is recommended. Treatment options include complete or partial resection followed by adjuvant radiotherapy.Key Words: Skull base, Meningioma, Hyperostosis, Fibrous dysplasia CASE REPORTA 48-year-old woman presented with a 3-year history of progressive right sided visual disturbance, exophthalmus, diplopia and eye pain. The patient underwent a cranial CT scan which showed a diffuse bilateral frontal and skull base hyperostosis, especially evident on the right side, and extending bilaterally from the sphenoid bones, down to the clinoid processes, orbits, temporal bones and the right frontal bone as seen in Figure 1. The right optic nerve was displaced with narrowing of the optic canal. These findings were consistent with fibrous dysplasia. Diffuse hyperostosis could also be consistent with an osteosarcoma, although this was less likely. The mass effect of the tumor involving both orbits caused compression of the eye muscles with subsequent exophthalmos, also more evident on the right side. The general practitioner referred the patient to an ophthalmologist who diagnosed exophthalmos with compressive optic nerve atrophy, decreased vision and secondary glaucoma. The ophthalmologist then referred the patient to an ENT doctor.The patient underwent surgical decompression of the right orbit via a transethmoidal, transsphenoidal and transpalpebral approach. During the operation, visualization of the orbital content was inadequate and bleeding from the bone prevented completion of the planned operation. The ENT suggested a second operation via a right subfrontal craniotomy to further decompress the orbit and the optic nerve. The first histopathological analysis seemed to confirm the suspicion of fibrous dysplasia and the patient was discharged. Ophthalmological and radiological follow-up was conducted via CT and MRI.
