“…The existence of neurological signs could be related to a large intracranial extension of the tumor causing nerve compression [6,9]. Exophthalmia and / or visual troubles related to spheno temporo-orbital location of intraosseous meningiomas were the most noted physical signs in the literature [5,7,9] Authors [2][3][4][5] agree on the polymorphic and non-specific aspect of the lesion on imaging. Thus two forms have been described: the form called hyperostosis is the most common, and the osteolytic or erosive form.…”

Introduction. Meningiomas are rare tumors in children, in whom the intracranial pathology is dominated by craniopharyngiomas and medulloblastomas. Cystic meningiomas are also rare, as is their intraosseous location. Intraosseous meningiomas are ectopic meningiomas. Their diagnosis is rarely done preoperatively. We report a case of cystic intraosseous meningioma managed in our department. Observation. Mr. ON, 16 years old, presented progressively a right temporal tumefaction causing an aesthetic prejudice. This tumefaction raised the flag of the right ear. It was covered by normal skin and there was moderate right hypo acoustics. CT scan showed a right sphenotemporal lesion with hyperdense contours and hypodense contents. It repressed the brain without invading it but affected the anatomic structures of the ear. Surgical procedure allowed for almost complete excision of the lesion. Histology of the operative specimen concluded to an intraosseous meningothelial meningioma. After a 4-year follow-up, the tumor residue remained stable. Conclusion. In addition to the diagnostic difficulty, we faced two other therapeutic difficulties. The first is that complete excision was not possible to avoid compromising a hearing always good. The second difficulty was related to the age of the patient who did not allow us to consider the cranial plasty before the end of the growth.

“…Primary interosseous meningiomas develop from intraosseous meningeal cells. It may be either multipotent mesenchymal cells that differentiate into meningocytes; or sequestration of meningocytes during suture fusion during intra-uterine development or during head injury with fracture [6][7][8].…”

Primary intraosseous meningioma is a rare variety of meningioma that represents about 1% of all meningiomas Intraosseous or intradiploic meningioma of the pediatric orbital roof is reported in case reports in very isolation.. The following article is carried out with the objective of describing a case of primary intraosseous meningioma of orbital roof in a pediatric patient as well as reviewing the literature in this regard. It was concluded that intraosseous or intradiploic meningioma of the orbital roof is a rare entity. They are more frequent in males and the common age of presentation is at the beginning of the second decade of life. They usually only present with ipsilateral proptosis, without impaired visual acuity or pain. Most are histologically of the psammomatous variety and the treatment of choice is total surgical excision.
