Long-term outcome of Simpson IV meningioma resection: Would it improve with adjuvant SRS?

Clin Neurol Neurosurg 2021 Jun 17;207:106766. Epub 2021 Jun 17.

Department of Neurosurgery and Neurooncology, First Faculty of Medicine, Charles University and Military University Hospital, Prague, Czech Republic; First Faculty of Medicine, Charles University in Prague, Prague, Czech Republic.

Objective: Subtotal meningioma resection (STR) is often performed to minimize surgical morbidity. Nevertheless, only a few studies have reported on patient outcome after STR. We studied the long-term outcome of SIV (Simpson grade IV) resection and identified predictive factors of overall survival (OS), progression-free survival (PFS) and time to progression (TTP).

Biomarkers for differentiating grade II meningiomas from grade I: a systematic review.

Br J Neurosurg 2021 Jun 21:1-7. Epub 2021 Jun 21.

Faculty of Health: Medicine, Dentistry and Human Sciences, The Institute of Translational and Stratified Medicine, University of Plymouth, Plymouth, UK.

Introduction: There are a number of prognostic markers (methylation, CDKN2A/B) described to be useful for the stratification of meningiomas. However, there are currently no clinically validated biomarkers for the preoperative prediction of meningioma grade, which is determined by the histological analysis of tissue obtained from surgery. Accurate preoperative biomarkers would inform the pre-surgical assessment of these tumours, their grade and prognosis and refine the decision-making process for treatment. Read More

A case series of percutaneous transforamen ovale biopsies in cavernous sinus lesions.

Acta Neurochir (Wien) 2021 Jun 16. Epub 2021 Jun 16.

Department of Neurosurgery, Bordeaux University Hospital Center, Pellegrin Hospital, Place Amélie Raba-Léon, 33076, Bordeaux, Cedex, France.

Background: The majority of cavernous sinus lesions are meningiomas, for which treatment (fractioned radiotherapy or radiosurgery), if indicated, is usually initiated upon image-based diagnosis. However, this region can be affected by a wide variety of pathological processes and the risk of misdiagnosis exists. As pathological diagnosis can be obtained by biopsy through the foramen ovale in selected cases, we asked the question as to whether systematically performing this procedure before treatment would provide additional, relevant diagnostic information.

Advances in Multidisciplinary Management of Skull Base Meningiomas.

Cancers (Basel) 2021 May 28;13(11). Epub 2021 May 28.

Maxillofacial Surgery Department, Department of Medicine, Santa Maria della Misericordia University Hospital, 33100 Udine, Italy.

The surgical management of Skull Base Meningiomas (SBMs) has radically changed over the last two decades. Extensive surgery for patients with SBMs represents the mainstream treatment; however, it is often challenging due to narrow surgical corridors and proximity to critical neurovascular structures. Novel surgical technologies, including three-dimensional (3D) preoperative imaging, neuromonitoring, and surgical instruments, have gradually facilitated the surgical resectability of SBMs, reducing postoperative morbidity.

Department of Biomedical Engineering, University of Alabama at Birmingham (UAB), 1825 University Blvd, Birmingham, AL 35294, USA.

Meningiomas are primary tumors of the central nervous system with high recurrence. It has been reported that somatostatin receptor 2 (SSTR2) is highly expressed in most meningiomas, but there is no effective targeted therapy approved to control meningiomas.

A case report of primary pulmonary meningioma masquerading as lung metastasis in a patient with rectal carcinoma: role of F-FDG PET/CT.

J Cardiothorac Surg 2021 May 29;16(1):153. Epub 2021 May 29.

Ningbo PET/CT center, Hwa Mei Hospital, University of Chinese Academy of Sciences, Ningbo, China.

Background: Primary pulmonary meningioma (PPM) is an extremely rare disease, which is often misdiagnosed as lung metastasis. Previous studies indicated that PPM usually showed homogeneous enhancement on enhanced CT and high uptake of F-fluorodeoxyglucose (F-FDG) on positron emission tomography/CT (PET/CT). In this study, we report a case of PPM with atypical enhanced CT and F-FDG PET/CT features in a patient with rectal carcinoma. Read More

IgG4-Related Inflammatory Pseudotumor Involving the Clivus: A Case Report and Literature Review.

Front Endocrinol (Lausanne) 2021 30;12:666791. Epub 2021 Apr 30.

Department of Neurosurgery, Xuanwu Hospital Capital Medical University, Beijing, China.

IgG4-related inflammatory pseudotumors are very uncommon and are characterized histologically by the presence of inflammatory swellings with increasing IgG4-positive plasma cells and lymphocytes infiltrating the tissues. As reports of intracranial IgG4-related pseudotumors are very rare, we report a case of an IgG4-related inflammatory pseudotumor involving the clivus mimicking meningioma. A 46-year-old male presented with intermittent headache for 2 years and a sudden onset of dysphagia and dysphonia of 7 days' duration along with lower limb weakness. Read More
