A Rare Case of Intra-Osseous Meningioma of the Sphenoid Bone - A Case Report

Abstract

A 42-year-old female patient presented with loss of vision and proptosis of her right eye. Computerized tomography (CT) scan revealed hyperostotic lesion involving the right sphenoid ridge, anterior clinoid process and roof and lateral wall of orbit with mass effect on the intraorbital contents. CT findings were suggestive of intra-osseous meningioma arising from right sphenoid bone. Later, MRI of the brain and orbit and histopathology of the lesion confirmed the case as an intra-osseous meningioma of the sphenoid bone. Though meningioma of tuberculum sella and primary calvarial meningioma were reported earlier, intraosseous meningioma of the sphenoid bone is rare.Ibrahim Med. Coll. J. 2012; 6(2): 73-75

Hyperostosis of the Frontal, Temporal, and Sphenoid Bones: Case Report and Review of Literature

“…However, this hypothesis is not coherent with the present case in which the sphenosquamosal suture is spared. Furthermore, a majority of the primary sphenoid extradural meningiomas found in the literature are unilateral [16,17,4,10]. The current patient presented with bilateral sphenotemporal hyperostosis.…”

“…HFI is usually an incidental finding and is not known to cause clinical disease [2], although excessive growth can be symptomatic upon brain tissue compression and/or cranial nerve entrapment [3]. Hyperostosis of the sphenoid bone or other bones comprising the floor of the cranium are rare and are generally seen unilaterally in association with intraosseous meningiomas [4,5]. Presently, we discuss a rare case involving hyperostosis of the sphenoid and temporal bones found during routine gross anatomy laboratory cadaveric dissection.…”

Primary intraosseous meningioma: a case report

“…2 A rare case of intra-osseous meningioma of the sphenoid bone of a 42-year-old female patient was reported in 2012. 8 Although rare, primary intraosseous meningiomas should be considered in the differential diagnosis of bone lesions, specially in women 5 when the lesions are osteoblastic and located in the cranial vault. CT and MRI are useful in preoperative radiological assessment of primary intraosseous meningiomas which can be treated successfully by surgical resection.…”
