Pure posterior chordoid foramen magnum meningioma: A case report and review of literature.

ABSTRACT:

Introduction and importance

Meningiomas are extra-axial central nervous system (CNS) tumors that arise from the arachnoid cells of the dura mater. Only 1.8-3.2% of all meningiomas are located at foramen magnum (FM) and pure posterior FM meningioma are very rare. The diagnosis of malignancy in patients with meningiomas has been a controversial issue. Only a histological study can confirm this situation.

Case presentation

We report a case of A 52-year-old female presented with a history of neck pain with progressive spastic quadriparesis.

Clinical discussion

Magnetic resonance imaging MRI T1 and T2 weighted images revealed well-defied pure posterior foramen magnum Lesion. Although the lesion was very sticky to neurovascular components. Simpson grade I was achieved. Histopathology revealed Chordoid meningioma. The patient had a dramatic recovery.

Conclusion

Although choroid meningioma is usually well circumscribed, sticky tumors should be suspected. Recurrence of Chordoid meningioma should be suspected. Total excision should be achieved and routine follow-up should be informed. Reports about chordoid meningioma aren't common, but reports on choroid foramen magnum meningioma are very rare. The opportunity to give the patient a symptom-free and normal life should not be missed in such cases.

Complete resection of pure anterior foramen magnum meningioma without neurovascular injuries poses a big challenge: Case report.

Project description:Introduction and importanceMeningiomas are common neoplasms representing 14.3-19% of all intracranial tumors. Among all the meningiomas, only 1.8-3.2% arises at the foramen magnum (FM) level.Most of the lesions (68%-98%) arising anterolaterally, followed by postolateral, purely posterior and, more rarely, purely anterior.Case presentationWe report a case of A 42-year-old female presented with a history of neck pain with progressive spastic hemiparesis.Clinical discussionMRI revealed well-defied pure anterior and on both sides of vertebral artery, foramen magnum lesion. Through conservative transcondylar approach, Lesion was removed totally in a piecemeal fashion. Histopathology revealed meningothelial meningioma. The patient had a dramatic recovery.ConclusionThe exposure allowed by the far-lateral retrocondylar or partial transcondylar approach is adequate for resecting even anterior intradural FMMs.Reports about Foramen magnum meningioma aren't common, but reports on pure anterior foramen magnum meningioma are very rare. The prerequisite for treating FM meningiomas (FMMs) is the perfect knowledge of the surgical anatomy. The opportunity to give the patient a symptom-free and normal life should not be missed in such cases.

Foramen magnum meningioma: Dysphagia of atypical etiology.

Project description:INTRODUCTION: We present a case of a foramen magnum meningioma that highlights the importance of the neurologic exam when evaluating a patient with dysphagia. A 58-year-old woman presented with an 18-month history of progressive dysphagia, chronic cough and 30-pound weight loss. Prior gastroenterologic and laryngologic workup was unrevealing. RESULTS: Her neurologic examination revealed an absent gag reflex, decreased sensation to light touch on bilateral distal extremities, hyperreflexia, and tandem gait instability. Repeat esophagogastroduodenoscopy was normal, whereas laryngoscopy and video fluoroscopy revealed marked hypopharyngeal dysfunction. Brain magnetic resonance imaging demonstrated a 3.1 x 2.7 x 2.9 cm foramen magnum mass consistent with meningioma. The patient underwent neurosurgical resection of her mass with near complete resolution of her neurologic symptoms. Pathology confirmed diagnosis of a WHO grade I meningothelial meningioma. CONCLUSION: CNS pathology is an uncommon but impressive cause of dysphagia. Our case demonstrates the importance of a thorough neurologic survey when evaluating such a patient.

Genomic Analysis of Posterior Fossa Meningioma Demonstrates Frequent <i>AKT1 E17K</i> Mutations in Foramen Magnum Meningiomas.

Project description:Objective Posterior fossa meningiomas are surgically challenging tumors that are associated with high morbidity and mortality. We sought to investigate the anatomical distribution of clinically actionable mutations in posterior fossa meningioma to facilitate identifying patients amenable for systemic targeted therapy trials. Methods Targeted sequencing of clinically targetable AKT1 , SMO , and PIK3CA mutations was performed in 61 posterior fossa meningioma using Illumina NextSeq 500 to a target depth of >500 × . Samples were further interrogated for 53 cancer-relevant RNA fusions by the Archer FusionPlex panel to detect gene rearrangements. Results AKT 1 ( E17K ) mutations were detected in five cases (8.2%), four in the foramen magnum and one in the cerebellopontine angle. In contrast, none of the posterior fossa tumors harbored an SMO ( L412F ) or a PIK3CA ( E545K ) mutation. Notably, the majority of foramen magnum meningiomas (4/7, 57%) harbored an AKT1 mutation. In addition, common clinically targetable gene fusions were not detected in any of the cases. Conclusion A large subset of foramen magnum meningiomas harbor AKT1 E17K mutations and are therefore potentially amenable to targeted medical therapy. Genotyping of foramen magnum meningiomas may enable more therapeutic alternatives and guide their treatment decision process.

Endoscopic far-lateral supracerebellar infratentorial approach for resection of posterior clinoid meningioma: Case report and literature review.

Project description:IntroductionThe surgery of posterior clinoid meningioma (PCM) remains one of the most formidable challenges for neurosurgeons because of its location at great depth in the cranium and proximity to vital neurovascular structures. Herein, we aim to describe the technique and feasibility of a novel approach, the purely endoscopic far-lateral supracerebellar infratentorial approach (EF-SCITA), for resection of this extremely rare entity.Case descriptionA 67-year-old women presented with gradually deteriorating vision in right eye for 6 months. Imaging examinations revealed a right-sided PCM, and the EF-SCITA approach was attempted for tumor resection. Tentorium incision allowed a working corridor toward the PCM in the ambient cistern through the supracerebellar space. During surgery, the infratentorial part of the tumor was found to compress the CN III and posterior cerebral artery medially and encase the CN IV laterally. Following debulking of the infratentorial tumor, the supratentorial part could be exposed and then excised, which had dense adhesions to the ICA and the initial part of the basal vein in front. After total tumor removal, its dural attachment was detected at the right posterior clinoid process and then coagulated under direct vision. The patient on follow-up at 1 month had improvement in visual acuity in right eye, with no restriction of extra-ocular movements.DiscussionEF-SCITA approach combines advantages of the posterolateral approach and endoscopic technique, allowing access to PCMs with seemingly low risks of postoperative morbidity. It would be a safe and effective alternative for resection of lesions in the retrosellar space.

Treatment and molecular analysis of bullous pemphigoid with tofacitinib: a case report and review of current literature

Project description:Bullous pemphigoid (BP) is a rare, life-threatening autoimmune blistering disease with pruritus and tension blisters/bullous as the main clinical manifestations. Glucocorticosteroids are the main therapeutic agents for it, but their efficacy is poor in some patients. Tofacitinib, a small molecule agent that inhibits JAK1/3, has shown incredible efficacy in a wide range of autoimmune diseases and maybe a new valuable treatment option for refractory BP. To report a case of refractory BP successfully treated with tofacitinib, then explore the underlying mechanism behind the treatment, and finally review similarities to other cases reported in the literature. Case report and literature review of published cases of successful BP treatment with JAK inhibitors. The case report describes a 73-year-old male with refractory BP that was successfully managed with the combination therapy of tofacitinib and low-dose glucocorticoids for 28 weeks. Immunohistochemistry and RNA sequencing were performed to analyze the underlying mechanism of tofacitinib therapy. A systematic literature search was conducted to identify other cases of treatment with JAK inhibitors. Throughout the 28-week treatment period, the patient experienced clinical, autoantibody and histologic resolution. Immunohistochemical analysis showed tofacitinib significantly decreased the pSTAT3 and pSTAT6 levels in the skin lesions of this patient. RNA sequencing and immunohistochemical testing of lesion samples from other BP patients identified activation of the JAK-STAT signaling pathway. Literature review revealed 17 previously reported cases of BP treated with four kinds of JAK inhibitors successfully, including tofacitinib (10), baricitinib (1), upadacitinib (3) and abrocitinib (3). Our findings support the potential of tofacitinib as a safe and effective treatment option for BP. Larger studies are underway to better understand this efficacy and safety.

Occurrence of Chordoid Glioma With Sodium Ion Metabolism Disorder 5 Years After Meningioma Surgery and Whole-Exome Sequencing: A Case Report and Literature Review.

Project description:Chordoid glioma (CG), a rare slow-growing brain tumor, mainly occurs in the region of the third ventricle. Although its degree of malignancy is relatively low, its clinical prognosis is poor due to obscure clinical manifestations and the particular growing position. Currently, gross total resection is the best available method for treatment of CG. However, the tumor is located in the deep structure of the brain and close to neurovascular structure so it is difficult to remove completely. This study reported a case of CG of the third ventricle 5 years after surgery of right frontal parietal fibrous meningioma, accompanied with peri and post-operative sodium ion metabolism disorder. Whole-exome sequencing (WES) revealed 25 gene mutations shared by meningioma and CG. In addition, the PRKCA D463H CG marker gene mutation also existed in this patient. We reviewed the latest literature on this rare brain tumor, summarized its clinical manifestations, imaging and pathological characteristics, and discussed the mechanism related to its occurrence and the reasons for sodium ion disorder.

A case report of surgical management of hemangiopericytoma at the foramen magnum.

Project description:Hemangiopericytoma (HPC) is a highly vascularized mesenchymal tumor known for its high rates of recurrence and metastasis. The extent of tumor removal is known to be the most trustful prognostic factor. Skull base HPCs are challenging to treat because of the difficulty of the surgical approach and proximity to vital vascular and neuronal structures. We successfully treated a case of HPC at the ventral foramen magnum through surgical gross tumor removal via a far-lateral transcondylar approach.A 38-year-old male complained of neck pain and bilateral paresthesia of his shoulders for 2 months, for which he was referred to our hospital. A magnetic resonance image (MRI) showed a 20 mm diameter mass at the ventral foramen magnum, which compressed his medulla oblongata. The tumor was gross totally removed via a far-lateral transcondylar approach. During the surgery, marked bleeding disturbed the surgical field until the main feeding artery from the direction of the dura mater was coagulated and cut. A relatively wide surgical field and a transcondylar approach were helpful to control the bleeding. The pathological examination revealed the tumor to be a HPC. After an uneventful recovery period of 9 days, the patient was discharged without neurological sequelae.We successfully and completely removed an HPC near the foramen magnum, employing a wide surgical field and a transcondylar approach to help control bleeding. When the tumor is suspected preoperatively to be a hemangiocytoma or vascular-rich tumor, a surgical approach that can secure a wide surgical field should be selected.

Primary intraosseous osteolytic meningioma: a case report and review of the literature.

Project description:BackgroundPrimary intraosseous meningioma is a subset of extradural meningioma that arises in the bone, and only a few cases have been reported to date.Case presentationAn 80-year-old man presented with decreased hearing on the right side accompanied by a disturbance of balance 10 months prior to admission. Magnetic resonance imaging revealed an 8 × 7 cm osteolytic mass in the right posterior fossa related to the petrous bone, with extension to the cervical region. During surgery, the tumor was found to be located extradurally, with no invasion of the dura. The tumor was removed entirely, apart from a small portion around the jugular foramen to avoid lower cranial nerve injury.ConclusionThe final diagnosis was primary intraosseous osteolytic meningioma with atypical pathology. Here, we report a rare case of an osteolytic skull lesion in the skull base not invading the dura and with extensive bone destruction.
