These tumors carry a high rate of recurrence, due to frequent bone involvement, cavernous . The authors review their experience with resection of sphenoid wing meningiomas at a single center, to examine whether this classification predicts clinical presentation and postsurgical outcome. Meningiomas are central nervous system tumours, arising from the meninges (Whittle et al. In some cases, deletions involving chromosome 22 are involved. Dr. John Golfinos performs surgery. Sphenoid wing meningioma is a large group with characteristics associated with skull base meningiomas and convexity meningiomas. En plaque meningiomas of the sphenoid wing, also called spheno-orbital meningiomas, present with such ocular manifestations ( Fig. A, The neck is slightly retroflexed, and the head is rotated 45 degrees to the right and fixed in a Mayfield clamp.The burr holes and saw cuts for the craniotomy are outlined in violet.. B, A pterional craniotomy including thorough drilling of the lesser . All instruments should be removed from the surgical field to give the eye time to recover before continuing with surgery. The extent of bony removal necessary and the optimal reconstruction strategy to prevent enophthalmos is debated. 9. Diagnosis Standard x-rays are often valuable in detecting meningiomas. 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. Several minutes later, while subsequent stages of the surgery were being performed, the blood stream perforated an undermined arterial wall. Early surgical intervention is often preferred for younger patients and healthy elderly patients, while observation is typically preferred for asymptomatic older patients with multiple medical problems [12]. Sphenoid wing meningioma Meningiomas that grow from the dura mater of the sphenoid ridge are a classic subtype of the skull base meningiomas. Surgeons may perform a craniotomy, a procedure to open the skull, for a meningioma found on the brain's surface. Craniotomy may also be used for tumors found in some areas of the skull base, such as near the brainstem, where the brain meets the spinal cord. It originates from the dura mater, the tissue enwrapping the brain and spinal cord. In addition, they can cause loss of sensation in the face, or facial numbness. Stereotactic radiosurgery is an option for asymptomatic small tumors without mass effect, but the proximity of highly radiosensitive optic chiasm and nerves often precludes its use. 2004).Spheno-orbital meningiomas (SOM) represent 9-18% of all meningiomas (Cushing & Eisenhardt 1939; Maroon et al. Methods: We reviewed the charts of 38 consecutive patients with sphenocavernous, clinoidocavernous, and sphenoclinoidocavernous meningiomas who underwent surgical treatment. Therefore, the diagnosis is determined by this particular growing pattern rather than histological appearance. 1,2 The incidence of hyperostosis in sphenoid wing meningiomas approaches 90%, 3,4 and histopathologic studies have revealed that the hyperostosis is due to meningiomatous infiltration of the bone . Reported 313 pts operated for meningioma b/w 1903- 1932 10/10/16 2 3. Side effects of treatment. A haemorrhage . 8.2). The figures listed above are . Definition. 1938- Cushing and Eisenhardt published : The Meningiomas, Their Classification, Regional Behaviour, Life History, Surgical End Results. Hence, meningiomas of the lateral sphenoid wing are often . Due to invasion of the periorbita, especially at the level . Tumor was foumd incidentally and im not having major sympto The sphenoid ridge meningioma account approximately 20% of all supra-tentorial meningioma, on the other hand the half of it occurred in the medial sphenoid ridge [5]. For many meningioma patients, seizures are the presenting symptom ( Chow et al . 2016) and are characterized by substantial hyperostosis of the sphenoid wing with an en-plaque carpet-like soft-tissue component (Li et . The general risks of cranial surgery include clot in the leg/clot in the lung ('DVT/PE') 1:100, infection 1:100, stroke/blood clot (with the possibility of permanent paralysis and also having a small . 2009; Leroy et al. The cornerstones of therapy for sphenoid wing meningioma involve observation, surgery, radiation therapy and chemotherapy. I would say that two months after surgery I was 90-95% recovered and on my way to virtually full recovery within another month or two. [ 3 8 10 ] we herein report an extremely rare case of a patient who improved from long-term blindness caused by A dural tail appears in 65% of meningiomas. Twenty-two patients were treated for sphenoid wing meningiomas by resection and reconstruction with split calvarial bone graft and, for more than half of the patients, also with free abdominal fat graft. GLOBOID MENINGIOMAS (1) deep, inner, or clinoidal (2) middle or alar (3) lateral, outer, or pterional. Introduction. The third case of intraoperative internal carotid artery injury occurred during recurrent middle sphenoid ridge meningioma surgery which required all of the intracranial parts of the internal carotid artery to be liberated from the tumour. This landmark is called the pterion. Surgery In this retrospective study, we determined the efficacy of total resection of meningiomas that invade the cavernous sinus but are restricted to the lateral compartment. Although this aspect of surgery is not often given the attention it deserves, it is a very real possibility for those faced with a serious operation. Spheno-orbital meningiomas are mainly defined as primary en plaque tumors of the lesser and greater sphenoid wings, invading the underlying bone and adjacent anatomical structures. Please compare Figure 32-3 for radiologic findings. Follow-up clinical exams, as well as neuroimaging, can aid in detecting recurrences. In addition, it also revealed en plaque meningioma involving the right medial sphenoid wing [Figure 2] with right intraorbital extension in the axial image. Sphenoid wing en plaque meningiomas are a clinical and pathological subgroup of meningiomas defined by its particular sheet-like dural involvement and its disproportionately large bone hyperostosis. Introduction . The results of surgery and other adjuvant treatments are heterogeneous. Meningiomas have two growth patterns: meningioma en masse which forms a space-occupying lesion and meningioma en plaque, which is a flat spreading tumor. Many meningiomas are highly vascular and may be embolized . My surgery was March 21, 2015. Alexander Engelmann and his collaborators published in 2021 an interesting case-report of an 86-year-old right-handed male with a complex oncological and neurosurgical pathology (history of colon adenocarcinoma, surgically treated, and recent surgery for right sphenoid wing meningioma), which presented in their emergency department with several transient episodes of fluent aphasia, during at . The sphenoid ridge separates the anterior from the middle cranial fossa and is related to the sphenoid segment of the sylvian fissure and the M1 segment of the middle cerebral artery. These can appear in a number of locations . Clinical outcomes including postoperative quality of life and recurrence rate were evaluated. A meningioma is a non-glial cell growth arising from the arachnoid meningothelial cells within the meninges. Surgical resection is . In reviewing the authors' series of giant sphenoid wing meningiomas, the goal was to evaluate how the extent of the tumor's invasion of surrounding . The clinical materials of 53 patients with sphenoid wing meningiomas treated microsurgically between January 2008 and January 2012 were analyzed retrospectively. Epidemiology Sphenoid wing meningiomas, or ridge meningiomas, are the most common of the basal meningiomas. Surgical resection is the mainstay of treatment for lateral sphenoid wing meningiomas, and the goal of surgery is complete removal of the tumor with wide excision of the affected bone and dura, minimizing the risk for future tumor recurrence. Sphenoid Wing Meningiomas: Surgical Outcomes in a Series of 141 Cases and Proposal of a Scoring System Predicting Extent of Resection World Neurosurg. I did exercises to strengthen my left hand but had no lasting impairment. Around 90% of meningiomas occur within the cranium, with 25% around the falx cerebri, 20% on the convexity, and 20% on the sphenoid wing. Sphenoid wing meningiomas (SWM) are known to present with intraosseous growth in a higher percentage than meningiomas in other locations. 2019 May;125:e48-e59. Request PDF | On Oct 17, 2022, M. May and others published Microsurgical resection of the meningiomas of the skull base: a multicentric study | Find, read and cite all the research you need on . Background:Sphenoid wing en plaque meningiomas are a subgroup of meningiomas defined by its particular sheet-like dural involvement and its disproportionately large bone hyperostosis.En plaque meningiomas represent 2-9% of all meningiomas and they are mainly located in the sphenoid wing. As many meningiomas have receptors for progesterone, progesterone blockers are being investigated. Sphenoid wing (also called sphenoid ridge) Problems with vision, loss of sensation in the face, or facial numbness, and seizures. Tumors located here can become involved with the visual nerves or surround a key artery. Case Discussion. Herein, the authors present their surgical outcomes and reconstruction results . She was given the option of surgery or gamma knife, she . In the base of the skull: Another challenging presentation is a skull base meningioma that grows near . It is advisable to have an ophthalmologist assist to help monitor the eye. A meningioma is an intracranial or an intravertebral tumor that develops in the meninges or layers of connective tissue surrounding the organs of the central nervous system. You should know the size and location of the tumor, any preop deficits and if the patient is at risk for increased ICP. o Matthew C Findlay BS, University of Utah School of Medicine, Salt Lake City, UT, USA o Jayson R Nelson BS, University of Utah School of Medicine, Salt Lake City, UT, USA o Sawyer Bauer BS, Univers Coupled with . On MRI it is isointense on both T1 and T2 images to grey matter, and again demonstrates enhancement. The intricate location of medial sphenoid wing meningiomas (mSWM) increases the risk of surgery, leading to higher morbidity and even mortality.It is crucial to study preoperative imaging to predict which extent of resection can be achieved and decide whether to manage total resection for lower recurrence rate or partial resection for preservation of encased neurovascular structures. Its lateral end joins the frontal, parietal, and temporal bone. But I didn't fall or have much difficulty doing anything. sphenoid wing meningiomas 1. Meningioma survival rate Low grade (grade 1) More than 80% of people with this type of meningioma survive for 5 years or more after diagnosis. Compared to previous follow-up scans carried at 3 years before the current visit, a diagnosis of RIM was based on neuroimaging. DISCUSSION . Key words: sphenoid, meningioma, inner wing, surgery . Neurosurgeon Things to remember The brain is wrapped in membranes called meninges. 1994; Mirone et al. A recent meta-analysis considering data in literature since 2000 reports a total resection in 66-87 % of medial sphenoid wing meningiomas with zero mortality and 4-18 % morbidity [ 7 ]. Furthermore, malignant spinal meningiomas had higher ten-year survival rates (73%) than malignant brain meningiomas (55.7%). [12] In this case, the patient's meningioma was near the sphenoid wing, impinging upon the frontal lobe, so cognitive symptoms were the presenting features . The patients, mostly women in their fifties, generally present with a progressive, unilateral, and nonpulsatile proptosis, often associated with cosmetic deformity and optic nerve damage. Surgery for tumors in this spot can be tricky and demand an experienced neurosurgeon. Some people who have had a brain tumour can develop side effects of treatment months or years later, such as: cataracts. It was termed for the first time by Cushing and Eisenhardt . migraine attacks. Their surgical management is presented incorporating a radiological scoring system that predicts the . Olfactory groove meningioma - Loss of sense of smell; loss of vision (in cases where a tumor grows large enough to compress the optic nerve) Optic nerve sheath meningioma - Gradual loss of vision; color blindness; a bulging appearance in an affected eye. Request a consultation Sphenoid ridge meningiomas represent approximately 20% of supratentorial meningiomas, among which less than half arise from the medial ridge of the sphenoid. This feature is not specific for meningiomas but is highly suggestive. Its size is 2.6cm. 10. Olfactory groove: Loss of smell due to compression of the nerves that run between the brain and the nose, and if the tumor grows big enough, visual symptoms can be expressed due to compression of the optic nerve . Case Discussion. Of all cranial meningiomas, about 20% of them are in the sphenoid wing. OBJECTIVE Hyperostosing sphenoid wing meningiomas cause bony hyperostosis that may extend into the orbit, resulting in proptosis, restriction of extraocular movements, and/or compressive optic neuropathy. High grade (grade 3) Less than 60% with a high grade meningioma survive for 5 years or more after diagnosis. Sphenoid meningiomas (meningiomas growing on the optic nerve behind the eyes) can cause visual problems, including loss of patches within your field of vision, or even blindness.
