INTRODUCTION Spheno-orbital meningioma (SOM) is a complex and unique pathological condition that accounts for 9% of all intracranial meningiomas. [ 34, 39 ] These tumors originate from the dural sheath of the sphenoid bone and are characterized by their invasion into the orbit, optic canal, superior orbital fissure, and cavernous sinus Patient with a mass-like spheno-orbital meningioma with hyperostosis and a well-defined posterior orbital mass causing rectus muscle distortion and a dural mass with temporal lobe distortion seen in axial (A) and coronal (B) CT imaging and on T1 fat-suppression MRI with gadolinium contrast (C) To examine the efficacy of spheno-orbital meningioma (SOM) resection aimed at symptomatic improvement, rather than gross total resection, followed by radiation therapy for recurrence Spheno-orbital meningioma (SOM) is a rare intracranial tumor that arises at the sphenoid wing, extends into the orbit, and is associated with hyperostosis of the sphenoid bone. These tumors often invade important neurovascular structures around the orbital apex, superior orbital fissure, and cavernous sinus

Spheno-orbital meningiomas (SOMs) that account for 4 to 9% of all intracranial meningiomas represent a complex sub- group of skull base tumors that characteristically present with proptosis and visual deficits.1,2SOMs are distinct from other types of sphenoid wing meningiomas in that the tumor characteristically has two components—a en plaque type of meningioma associated with hyperostosis involving the bone around the orbit and sphenoid wing Spheno-orbital meningioma with unusual radiological features. Higuchi M(1), Tsuji M, Fujimoto Y, Ikeda H. Author information: (1)Department of Neurosurgery, Itami Municipal Hospital, Hyogo, Japan. We report a patient with a spheno-orbital meningioma having unusual clinical and radiological features Spheno-orbital meningiomas (SOMs) that account for 4 to 9% of all intracranial meningiomas represent a complex subgroup of skull base tumors that characteristically present with proptosis and visual deficits Medial sphenoid wing meningiomas are a heterogeneous group of tumors originating from the anterior clinoid and the medial third of the lesser sphenoid wing. This group includes both globular and hyperostotic en plaque tumors (also called spheno-orbital meningiomas) Conclusions: Spheno-orbital meningiomas may be classified according to the location and extent of the intraorbital tumor invasion. The different localizations may require different surgical approaches, with different chances of complete removal

Chapter 37 Spheno-Orbital Meningioma. The original description of sphenoid ridge meningiomas by Cushing and Eisenhardt in 1938 defines a global type, which grows outward into the sylvian fissure from its attachment, and an en-plaque type, which has a carpet-like growth pattern and evokes hyperostotic changes in the adjacent bone. 1 Since the. BACKGROUND: Internal variation among spheno-orbital meningiomas (SOM) is surgically challenging. Optic canal invasion management is discussed. METHOD: This retrospective study includes 70 patients with SOM who underwent surgery between 1995 and 2012. Preoperative ophthalmological, neurological and aesthetic clinical signs were collected A series of 15 patients who underwent neurosurgical procedures for recurrent spheno-orbital meningioma is reported. There were 11 women and four men, with a mean age of 46 years. The mean duration between the first and second operations was 46 months. Progressive proptosis without neurological deficit was the most common symptom Spheno-orbital meningiomas were historically treated by traditional craniotomies. However, in the past few years new endoscopic treatments have been successfully performed

Spheno-orbital meningiomas (SOM) account for only 4%-9% of all intracranial meningiomas . Due to the penetrative capabilities of SOMs, they can invade local structures, such as the orbit or cavernous sinus. Since these types of tumors can typically infiltrate such vital structures, surgical management can be increasingly difficult Sphenoorbital meningioma. Spheno-orbital meningiomas represent a delicate subtype of intracranial meningiomas involving the sphenoid wing, orbit and important neurovascular structures such as cavernous sinus, carotid artery or optic nerve.Insidious and aggressive dural, bone and orbital involvement contains several defiances to adequate resection, which provides high rates of recurrence Case Discussion. This case demonstrates strong radiological features in keeping with a sphenoid wing meningioma involving the region of the anterior clinoid, adjacent medial sphenoid wing, superior orbital fissure, and cavernous sinus.. It exerts a compressive effect on the adjacent skull foramina as compression on the optic nerve Spheno-orbital meningiomas (SOM) represent a subgroup of sphenoid ridge meningiomas that are also known as the en-plaque meningiomas account for 20% of intracranial meningiomas [1]. This location is considered to be the third most common location for meningiomas [2, 3]. En-plaque meningiomas with extension into the orbit repre

Background To investigate the natural history and the growth rate of spheno-orbital meningiomas (SOMs). Methods Ninety patients with a diagnosis of SOM were included, and patient charts and imaging were evaluated. In a subset of 32 patients, volumetric studies were performed. Results The median follow-up for the entire group was 4 years (range, 1-15); the mean age was 47.8 (range, 26-93. Spheno-orbital meningiomas (SOMs) account for 9-18 % of all adult intracranial meningiomas, and their natural history differs from other meningiomas [1, 2].These tumours are associated with a hyperostosis, which constitutes the main part of the tumour, predominantly on sphenoid bone that extends to the orbit and a widespread dural thickening, which is referred to as an en plaque invasion growth rate of spheno-orbital meningiomas (SOMs). Methods Ninety patients with a diagnosis of SOM were included, and patient charts and imaging were evaluated. In a subset of 32 patients, volumetric studies were performed. Results The median follow-up for the entire group was 4 years (range, 1-15); the mean age was 47.8 (range Spheno-orbital meningiomas will be discussed in the Lateral Sphenoid Wing Meningioma chapter. There are no specific pathologic or genetic features for medial sphenoid wing meningiomas. Some of these tumors are caused by ionizing radiation.

Spheno-orbital meningiomas represent a delicate subtype of intracranial meningiomas involving the sphenoid wing, orbit and important neurovascular structures such as cavernous sinus, carotid artery or optic nerve.Insidious and aggressive dural, bone and orbital involvement contains several defiances to adequate resection, which provides high rates of recurrence Sphenoid wing meningiomas are slow growing tumors that originate from outer arachnoid meningeal epithelial cells. Currently no definite environmental risk factors exist. Genetically, the most well characterized and common alteration is the loss of the NF2 gene (NF2) on chromosome 22q. NF2 encodes a tumor suppressor known as merlin grade II meningioma three years prior, who presented with worsening left-sided visual loss and pronounced temporal bossing. Repeat magnetic resonance imaging (MRI) revealed a recurrent left spheno-orbital tumor suggestive of a meningioma extending into the middle cranial fossa, the lateral orbit, and the temporalis muscle controlling the growth of meningioma (9, 10), particularly for skull base meningioma (11). However, the literature on spheno-orbital meningioma is very poor regarding postoperative radiotherapy. As yet, the additional benefit of postoperative radiotherapy for spheno-orbital meningiomas is unclear and requires further investigation

Spheno-Orbital Meningioma (Sphenoid Wing Meningioma

ObjectiveSpheno-orbital meningiomas (SOM) are rare intracranial tumors that arise at the sphenoid wing. These tumors can invade important neurovascular structures making radical resection difficult, while residual tumors often lead to recurrence. The purpose of this study was to evaluate prognostic factors influencing the recurrence and progression-free survival (PFS) rates of spheno-orbital. 9. Location of hyperstosis according to frequency lesser wing of the sphenoid bone the greater wing of the sphenoid The roof of the orbit the inferior orbital fissure the infratemporal fossa the orbital rim. 10. GLOBOID MENINGIOMAS (1) deep, inner, or clinoidal (2) middle or alar (3) lateral, outer, or pterional For example, a study of 47 patients with spheno-orbital meningioma who underwent surgery via the frontotemporal approach without orbital wall reconstruction showed that complete resection was achieved in 51% of cases.

OBJECTIVE: En plaque sphenoid wing meningiomas are complex tumors involving the sphenoid wing, the orbit, and sometimes the cavernous sinus. Complete removal is difficult, so these tumors have high rates of recurrence and postoperative morbidity. The authors report a series of 71 patients with sphenoid wing meningiomas that were managed surgically

Internal and external spheno-orbital meningioma varieties

Thirty to forty percent of all meningiomas arise from the base of the anterior or middle fossa with the potential to involve the orbit secondarily. Spheno-orbital meningiomas (SOMs) account for half of these tumors, and olfactory groove meningiomas (OGMs) and tuberculum sella meningiomas (TSMs) account for most of the remainder OBJECTIVE In meningiomas involving the orbit and optic canal, surgery is the mainstay of therapy. However, radical resection is often limited to avoid functional damage, so multidisciplinary treatment concepts are implemented. Data on the timing and value of early postoperative radiotherapy (PORT) are scarce. This retrospective study analyzes outcomes in patients who underwent targeted.
