Clinico-pathologic predictors of dismal course in atypical meningiomas: a retrospective single-centre analysis.

J Neurosurg Sci 2022 Jun 28. Epub 2022 Jun 28.

Department of Neurosurgery, Medical University of Vienna, Vienna, Austria -

Background: Despite continuous refinement of the WHO classification for meningiomas, the biological behaviour of atypical meningiomas remains difficult to predict on the basis of this grading system alone. The aim of this study was to investigate the prognostic significance of clinical and radiological parameters in a series of atypical meningioma with long follow-up of minimum 5 years.

Methods: Of 1675 meningiomas treated at the Medical University Vienna between 1993 and 2015, 179 were atypical meningioma. Read More

Bevacizumab is an effective treatment for symptomatic cerebral necrosis after carbon ion therapy for recurrent intracranial malignant tumours: A case report.

Mol Clin Oncol 2022 Jul 19;17(1):114. Epub 2022 May 19.

The First School of Clinical Medicine, Lanzhou University, Lanzhou, Gansu 730000, P.R. China.

Carbon ion therapy (CIT) is a form of particle therapy, which not only spares normal tissues but may also improve local control of recurrent intracranial tumours. Cerebral radiation necrosis (RN) is one of the most serious adverse reactions of recurrent brain tumours following reirradiation, which may lead to neurological decline or even death. Bevacizumab is an anti-vascular endothelial growth factor antibody, which has been used to treat symptomatic RN. Read More

somatic mosaicism in a patient with bilateral optic nerve sheath meningiomas: illustrative case.

J Neurosurg Case Lessons 2022 Jun 6;3(23):CASE2247. Epub 2022 Jun 6.

Departments of Ophthalmology.

Background: In the past decade, next-generation sequencing has spurred significant progress in the understanding of cytogenetic alterations that occur in meningiomas. Eighty percent of adult meningiomas harbor pathogenic somatic variants involving , , , , , or Somatic variants in associated with meningiomas usually localize to the gene's WD40 domains but are mutually exclusive to germline mutations, which cause a distinctive autosomal dominant syndrome.

Observations: This case involved a 15-year-old girl with bilateral optic nerve sheath meningiomas, diffuse meningiomatosis, and syndromic features, including craniosynostosis, brain anomalies, syndactyly, brachydactyly, epicanthus, and patent ductus arteriosus. Read More

Radiographic differentiation of secretory meningiomas and WHO grade 2 meningiomas: when atypical features are not always predictive of atypical tumors.

World Neurosurg 2022 Jun 17. Epub 2022 Jun 17.

Department of Neurological Surgery and Rosa Ella Burkhardt Brain Tumor & Neuro-Oncology Center, Cleveland Clinic, Cleveland, OH. Electronic address:

Objective: Secretory meningioma (SM) is a rare subtype of World Health Organization (WHO) grade 1 meningioma, associated with significant peritumoral brain edema (PTBE). Because of this, SM may be mistaken preoperatively to be a WHO grade 2 meningioma (G2M). In this study, we identified radiographic features to differentiate these two tumor types preoperatively to help inform surgical decision-making. Read More

Magnetic Resonance Imaging of Unusual Neoplasms Related to Foramen of Luschka: A Review for Differential Diagnosis.

Indian J Radiol Imaging 2022 Mar 19;32(1):71-80. Epub 2022 Apr 19.

Department of Neurosurgery, Bahçeşehir University School of Medicine, Göztepe Medical Park Training and Education Hospital, Istanbul, Turkey.

There are many types of neoplasms in or around the foramen of Luschka (FL), and definitive diagnosis in some cases requires knowledge of imaging findings. The uncommon and challenging neoplasms with FL involvement considered in this study are exophytic brainstem glioma, primary glioblastoma of the cerebellopontine angle (CPA), primary anaplastic ependymoma of the CPA, choroid plexus papilloma of the FL, solitary FL choroid plexus metastasis, extraskeletal myxoid chondrosarcoma of the jugular foramen, paraganglioma of the jugular foramen, exostosis of the jugular foramen, psammomatous meningioma in the lateral cerebellar medullary cistern, epidermoid tumor of the fourth ventricle, and a hypoglossal schwannoma. These neoplasms may have overlapping clinical and imaging features, but some have relatively distinct imaging features. Read More

Validity of magnetic resonance imaging (MRI) in the primary spinal cord tumors in routine clinical setting.

Sci Rep 2022 Jun 16;12(1):10151. Epub 2022 Jun 16.

Department of Neurosurgery, Seoul National University Hospital, Seoul, Republic of Korea.

MRI is the primary diagnostic modality for spinal cord tumors. However, its validity has never been vigorously scrutinized in daily routine clinical practice, where MRI tissue diagnosis is usually not a single one but multiple ones with several differential diagnoses. Here, we aimed to assess the validity of MRI in terms of predicting the pathology and location of the tumor in routine clinical settings. Read More

Evaluation of Magnetic Resonance Imaging for Microsurgical Efficacy and Relapse of Rolandic Meningioma.

Comput Intell Neurosci 2022 6;2022:1026494. Epub 2022 Jun 6.

Department of Neurosurgery, Changde First People's Hospital, Changde 415000, Hunan, China.

In this study, magnetic resonance imaging (MRI) was used to evaluate the relapse features of patients with Rolandic meningioma after the microsurgery. 53 patients with Rolandic meningioma were selected as the research objects, and they were divided into the relapse group ( = 16) and nonrelapse group ( = 37) according to whether patients had a relapse during the follow-up period. Differences in quality of life, H-MRS index, vascular density, and cell proliferation between the two groups were assessed as well as imaging differences between the two groups were analyzed using MRI.

Threshold field painting saves the time for segmentation of minute arteries.

Int J Comput Assist Radiol Surg 2022 Jun 11. Epub 2022 Jun 11.

Department of Neurosurgery, Graduate School of Medicine, The University of Tokyo, 7-3-1 Hongo, Bunkyo-ku, Tokyo, 113-8655, Japan.

Purpose: It is often time-consuming to segment fine structures, such as the cerebral arteries from magnetic resonance imaging (MRI). Moreover, extracting anatomically abnormal structures is generally difficult. The segmentation workflow called threshold field painting was tested for its feasibility in morbid minute artery segmentation with special emphasis on time efficiency. Read More

Meningioma Radiomics: At the Nexus of Imaging, Pathology and Biomolecular Characterization.

Cancers (Basel) 2022 May 25;14(11). Epub 2022 May 25.

Department of Advanced Biomedical Sciences, University of Naples "Federico II", Via Sergio Pansini 5, 80131 Naples, Italy.

Meningiomas are the most common extra-axial tumors of the central nervous system (CNS). Even though recurrence is uncommon after surgery and most meningiomas are benign, an aggressive behavior may still be exhibited in some cases. Although the diagnosis can be made by radiologists, typically with magnetic resonance imaging, qualitative analysis has some limitations in regard to outcome prediction and risk stratification.
