Additional Information The intracranial meningioma presumed to represent about 14 to 18% of all intracranial neoplasms. Histopathological analysis confirmed a chordoid meningioma (WHO grade II) with subtotal resection. 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 a tumour developing somewhere else. 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. Meningiomas are much more common in females, and are more common after 50 years of age. Non-malignant meningiomas of the spine conferred a better ten-year survival (96%) than non-malignant meningiomas of the cerebral meninges (83%). Methods: We reviewed the charts of 38 consecutive patients with sphenocavernous, clinoidocavernous, and sphenoclinoidocavernous meningiomas who underwent surgical treatment. 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 extent of bony removal necessary and the optimal reconstruction strategy to prevent enophthalmos is debated. 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 . Diagnosis Standard x-rays are often valuable in detecting meningiomas. sphenoid wing meningiomas 1. Object: Cushing and Eisenhardt were the first to describe sphenoid wing meningiomas in detail, categorizing globoid tumors into 3 groups: 1) medial; 2) middle; and 3) lateral. Follow-up clinical exams, as well as neuroimaging, can aid in detecting recurrences. These tumors can invade the lateral wall of the cavernous sinus, superior orbital fissure, floor of the middle cranial fossa, and the extracranial infratemporal fossa. 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. As many meningiomas have receptors for progesterone, progesterone blockers are being investigated. epilepsy. Multiple bur holes are then made around the invaded or hyperostotic bone to prevent excessive bleeding and dural tear. Neurosurgeon Things to remember The brain is wrapped in membranes called meninges. In the past, these tumors always required a traditional craniotomy, but we have developed and applied minimally invasive techniques using the transorbital approach in conjunction with . It is the middle layer or the arachnoid that usually gives rise to meningiomas. Around 90% of meningiomas occur within the cranium, with 25% around the falx cerebri, 20% on the convexity, and 20% on the sphenoid wing. She was given the option of surgery or gamma knife, she . 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. CT and MRI demonstrate characteristic appearances of a left sphenoid wing meningioma. Tumors located here can become involved with the visual nerves or surround a key artery. The cornerstones of therapy for sphenoid wing meningioma involve observation, surgery, radiation therapy and chemotherapy. Fluid-attenuation inversion recovery sequences (FLAIR) may demonstrate adjacent parenchymal oedema. It originates from the dura mater, the tissue enwrapping the brain and spinal cord. The most difficult area to dissect is the orbital component of sphenoid wing meningiomas. Ilica et al (2014) correlated CT and MRI imaging features with WHO histologic classification in 65 cases of IOM [8]. The mass is well circumscribed and extraaxial with a broad dural base. 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. The first surgical experience with meningiomas of the sphenoid ridge was reported in 1938 by Cushing and Eisenhardt. Request a consultation I did exercises to strengthen my left hand but had no lasting impairment. In addition, it also revealed en plaque meningioma involving the right medial sphenoid wing [Figure 2] with right intraorbital extension in the axial image. These tumors carry a high rate of recurrence, due to frequent bone involvement, cavernous . 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. Observation is also a reasonable treatment plan for small incidental tumors. Recovery was smooth, extubation uneventful and the patient was shifted to ICU for postoperative care. Hence, meningiomas of the lateral sphenoid wing are often . Meningiomas respond well to treatment, with eight out of 10 cases cured. Sphenoid Wing Meningioma is a tumor that arises on the meninges covering the bone on the side of the skull base. Tumor was foumd incidentally and im not having major sympto High grade (grade 3) Less than 60% with a high grade meningioma survive for 5 years or more after diagnosis. Several minutes later, while subsequent stages of the surgery were being performed, the blood stream perforated an undermined arterial wall. Surgery for a meningiomas within the skull involves a craniotomy, which means making a window in the bone in the skull to remove the tumour (see patient information leaflet on Craniotomy). Its lateral end joins the frontal, parietal, and temporal bone. In the base of the skull: Another challenging presentation is a skull base meningioma that grows near . 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. PDF | On Aug 14, 2019, Maryam Naser published Visual Recovery After Decompression Surgery of Skull Base Meningioma: A Case Report | Find, read and cite all the research you need on ResearchGate Meningiomas are slow-growing, expansile benign tumors that can involve the bone and dura. 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. [1,16,17,19,29] Nowadays, there is a trend to be less radical during the removal of skull base meningiomas due to concerns related to the quality of life of the patient and the goal of reducing the . The patient's findings were consistent with a left sphenoid wing meningioma. 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. Much depends on your individual tumor and your doctor will be able to give you a better idea of what exactly you can expect. Introduction . hearing loss. 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. Skinner and pearce . Some people who have had a brain tumour can develop side effects of treatment months or years later, such as: cataracts. Those that have grown to a very large size, encasing the major cerebral arteries, are associated with a high risk of stroke. Sphenoid wing meningiomas (SWM) are known to present with intraosseous growth in a higher percentage than meningiomas in other locations. This feature is not specific for meningiomas but is highly suggestive. A haemorrhage . Reported 313 pts operated for meningioma b/w 1903- 1932 10/10/16 2 3. 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 . 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]. She underwent a left pterional craniotomy with sphenoid wing meningioma resection and decompression of the left optic nerve. 1938- Cushing and Eisenhardt published : The Meningiomas, Their Classification, Regional Behaviour, Life History, Surgical End Results. Sphenoid ridge meningiomas represent approximately 20% of supratentorial meningiomas, among which less than half arise from the medial ridge of the sphenoid. 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. This portion of the dura mater is actually covering the lesser wing of the sphenoid bone from the anterior clinoid process (ACP) to the pterion. Sphenoid wing meningioma is a large group with characteristics associated with skull base meningiomas and convexity meningiomas. 8.2). Intraventricular meningioma - Unusual feeling of pressure within the head; wooziness. 9. 2004).Spheno-orbital meningiomas (SOM) represent 9-18% of all meningiomas (Cushing & Eisenhardt 1939; Maroon et al. On her one-week post operative exam, the patient complained of a left upper lid droop and the . infertility. DISCUSSION . 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. Depending on the grade and extent of resection, from less than 1 in 10 to over two-thirds of tumors will recur after surgical excision. Medial sphenoid wing meningiomas (mSWM) present a surgical challenge because they can grow into the cavernous sinus (CS), encircle the anterior circulation arteries, affect the cranial nerves, and . 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. 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. It is advisable to have an ophthalmologist assist to help monitor the eye. 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. OBJECTIVE Sphenoid wing meningiomas are a heterogeneous group of tumors with variable surgical risks and prognosis. 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. It exerts a compressive effect on the adjacent skull foramina as compression on the optic nerve. Meningiomas form around 30% of all brain tumours. The Simpson paper highlighted the importance of radical removal during the surgical treatment of meningiomas in the prevention of tumor recurrence and different series observed similar results. FIGURE 32-4 Surgery for a medium-sized meningioma of the left medial sphenoid wing. A meningioma is atumour that grows out of the meninges, for reasons unknown. It was termed for the first time by Cushing and Eisenhardt . Epidemiology Sphenoid wing meningiomas, or ridge meningiomas, are the most common of the basal meningiomas. Coupled with . Craniotomy for Excision of Meningioma (CPT 61512) General: Patients may be symptomatic or asymptomatic. Considering her age and underlying disease, we planned to avoid probable complications of an aggressive resection. These can appear in a number of locations . Some patients are able to return to work as soon as 2-4 weeks following surgery, but others will need a longer recovery period of 6-12 weeks. Many meningiomas are highly vascular and may be embolized . A dural tail appears in 65% of meningiomas. Their surgical management is presented incorporating a radiological scoring system that predicts the . GLOBOID MENINGIOMAS (1) deep, inner, or clinoidal (2) middle or alar (3) lateral, outer, or pterional. 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. Behind the eyes: Meningiomas can grow on the sphenoid wing, a shelf of bone in the middle of the head behind the eye. Clinical outcomes including postoperative quality of life and recurrence rate were evaluated. Due to invasion of the periorbita, especially at the level . [ 8] Surgeons may perform a craniotomy, a procedure to open the skull, for a meningioma found on the brain's surface. Preoperative Seizures in Meningioma. This is why prognosis for a meningioma is often an ongoing process, revised at different stages in your journey. [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 . [ 3 8 10 ] we herein report an extremely rare case of a patient who improved from long-term blindness caused by Sphenoid wing (also called sphenoid ridge) Problems with vision, loss of sensation in the face, or facial numbness, and seizures. Furthermore, malignant spinal meningiomas had higher ten-year survival rates (73%) than malignant brain meningiomas (55.7%). 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 ]. In some cases, deletions involving chromosome 22 are involved. On MRI it is isointense on both T1 and T2 images to grey matter, and again demonstrates enhancement. Side effects of treatment. One doctor said i should have surgery within 3-6 months.and another doctor just left it up to me to make a decision as to operate now or wait another 3 months and get an MRI and see if tumor is growing. Key words: sphenoid, meningioma, inner wing, surgery . Meningiomas are central nervous system tumours, arising from the meninges (Whittle et al. Surgery 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]. When meningioma involves the frontal lobes, symptoms of lassitude, apathy, psychomotor slowing, and impaired concentration may be historically indistinguishable from an affective episode. Dr. John Golfinos performs surgery. Sphenoid wing meningioma Meningiomas that grow from the dura mater of the sphenoid ridge are a classic subtype of the skull base meningiomas. The meninges consist of three layers. 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. Sphenoid wing meningiomas They originate from the lining that covers the lateral aspect of the sphenoid bone, located just deep to the temple and behind the eye. 10. Surgical resection is the mainstay of treatment for medial sphenoid wing meningiomas. 1994; Mirone et al. Definition. 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. Symptoms may be due to location of tumor or increased ICP. Symptoms depend on which part of the brain is affected, but can include headaches, seizures and partial paralysis. You should know the size and location of the tumor, any preop deficits and if the patient is at risk for increased ICP. Any surgery undertaken in patients with mitral valve disease is considered risky. 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 . Approximately 25% of patients with rheumatic heart disease manifest with pure mitral stenosis, while an additional 40%, have a combination of mitral stenosis and regurgitation [1]. doi: 10.1016/j.wneu . For many meningioma patients, seizures are the presenting symptom ( Chow et al . 10/10/16 1SW / OLFACTORY GROOVE MENINGIOMA 2. 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 . Therefore, the diagnosis is determined by this particular growing pattern rather than histological appearance. A meningioma is a benign brain tumor. Please compare Figure 32-3 for radiologic findings. A craniotomy is performed using general anesthesia. All instruments should be removed from the surgical field to give the eye time to recover before continuing with surgery. Surgery for tumors in this spot can be tricky and demand an experienced neurosurgeon. Sphenoid Wing Meningiomas: Surgical Outcomes in a Series of 141 Cases and Proposal of a Scoring System Predicting Extent of Resection World Neurosurg. But I didn't fall or have much difficulty doing anything. Herein, the authors present their surgical outcomes and reconstruction results . A recent systematic review combining data from 33 different studies published between 1980 and 2014 ( Table 18.1) found that approximately 29% of patients with meningioma experience seizures before surgery ( Englot et al., 2015 ). 1 These tumors arise from arachnoid cells of the perineural sheaths or the arachnoid layer of the meninges. 2019 May;125:e48-e59. En plaque meningiomas of the sphenoid wing, also called spheno-orbital meningiomas, present with such ocular manifestations ( Fig. there are several cases of postoperative visual recovery in patients with long-term decreased vision due to inner-third sphenoid wing meningioma, however, we found no reports of patients who improved from long-term blindness. A meningioma is a non-glial cell growth arising from the arachnoid meningothelial cells within the meninges. Its size is 2.6cm. Meningiomas have two growth patterns: meningioma en masse which forms a space-occupying lesion and meningioma en plaque, which is a flat spreading tumor. We are more than surgeons, we are your support system. Sphenoidal wing meningiomas are often associated with sphenoidal wing hyperostosis, are often invasive, and spread to the dura in the frontal, temporal, and orbital regions. 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. Case Discussion. Follow-up period ranged from 6 to 62 months (median, 34 months). My surgery was March 21, 2015. A meningioma on the sphenoid wing was found 2 months ago. The drill is then used to connect the bur holes and to remove the invaded. Brain imaging revealed a right-sided sphenoid wing meningioma with considerable edema around it. The results of surgery and other adjuvant treatments are heterogeneous. Introduction. Background: Surgical management of giant medial sphenoid meningiomas (> or =5 cm in maximum dimension) is extremely challenging due to their intimate relationship with vital neural structures like the optic nerve, cranial nerves of the cavernous sinus and the cavernous internal carotid artery. migraine attacks. 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. In addition, they can cause loss of sensation in the face, or facial numbness. Of all cranial meningiomas, about 20% of them are in the sphenoid wing. Surgical resection is . Case Discussion. It is isodense to brain on CT and enhanced relatively vividly. 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 . The figures listed above are . From the sphenoid wing, the tumor grows towards the temporal lobe causing significant temporal lobe brain compression and swelling or edema of the brain. Compared to previous follow-up scans carried at 3 years before the current visit, a diagnosis of RIM was based on neuroimaging. Meningiomas are typically benign and slow growing. 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. This landmark is called the pterion. 2009; Leroy et al. The tumor was first described in 1910 by Frotscher and Becker as an autopsy finding in a 72-year-old man. Owing to her cognitive decline and recent symptoms, it was decided to proceed with surgical resection of the lesion. There is today nothing in the whole realm of surgery more gratifyng than the succeessful removal of meningioma with . 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 . The clinical materials of 53 patients with sphenoid wing meningiomas treated microsurgically between January 2008 and January 2012 were analyzed retrospectively. Total surgical resection is difficult and therefore these tumors have high recurrence rates. 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. 2016) and are characterized by substantial hyperostosis of the sphenoid wing with an en-plaque carpet-like soft-tissue component (Li et . After undergoing any kind of major surgery, there may be many side-effects, not least of which is depression that can make the patient's recovery that much more excruciating [1]. problems with thinking, memory, language or judgement.
