Multi-parametric qualitative and quantitative MRI assessment as predictor of histological grading in previously treated meningiomas.

Neuroradiology 2020 Jun 24. Epub 2020 Jun 24.

Department of Clinical Surgical Diagnostic and Pediatric Sciences, University of Pavia, Pavia, Italy.

Purpose: Meningiomas are mainly benign tumors, though a considerable proportion shows aggressive behaviors histologically consistent with atypia/anaplasia. Histopathological grading is usually assessed through invasive procedures, which is not always feasible due to the inaccessibility of the lesion or to treatment contraindications. Therefore, we propose a multi-parametric MRI assessment as a predictor of meningioma histopathological grading. Read More

Venous anatomy of the infratentorial compartment.

Handb Clin Neurol 2020 ;169:73-86

Department of Neurological Surgery, University of California San Francisco, San Francisco, CA, United States. Electronic address:

Approximately 7%-12% of all intracranial meningiomas are located in the posterior fossa (PF), a region which contains-among many other critical neurovascular structures-numerous major veins and sinuses draining blood away from the PF structures. There is a growing body of evidence indicating that venous sacrifice or injury during surgery are linked to serious postoperative complications-which may lead to significant morbidity and mortality. Thus, it is of paramount importance that clinicians charged with the preoperative, surgical, and postoperative care of patients undergoing treatment for meningioma are familiar with the general anatomy of the PF veins, as well as their structural nuances and drainage variations.

Computed tomographic imaging of meningiomas.

Handb Clin Neurol 2020 ;169:167-175

Department of Neuroradiology, Royal Victoria Hospital, Belfast Health & Social Care Trust, Belfast, United Kingdom.

Although magnetic resonance imaging (MRI) has surpassed computerized tomography (CT) as the imaging modality of choice, there are certain instances when CT should be a preoperative requisite for meningioma surgical resection. Given its superior bone definition and the propensity for meningiomas to invade bone (as evidenced by hyperostosis on imaging), CT can be extremely helpful to the surgeon when planning and evaluating postoperatively the extent of bone removal during tumor resection. Advances in CT imaging also allow for visualization of the adjacent arterial and venous vasculature to determine feasibility of resection and likelihood of adjuvant treatments such as radiosurgery to a tumor residuum.

Somatostatin receptor-2 negative meningioma: pathologic correlation and imaging implications.

Clin Imaging 2020 Apr 25;66:18-22. Epub 2020 Apr 25.

Department of Radiology, Weill Cornell Medicine-New York Presbyterian Hospital, United States of America.

Meningiomas are the most common non-malignant primary intracranial tumors, accounting for nearly 40% of all primary brain tumors, usually expressing high levels of somatostatin receptors (SSTR), particularly SSTR2. Because Ga-DOTATATE targets SSTR2, it is increasingly used clinically for meningioma evaluation. While previous apparent lack of SSTR expression in meningiomas has been reported in isolated cases, these prior studies utilized Indium-111 (In) Octreotide, which is of lesser diagnostic accuracy compared to Ga-DOTATATE, as well as Technetium-99m (Tc)-DTPA scintigraphy, which necessitates an intact blood-tumor-permeability barrier.

Front Oncol 2020 16;10:427. Epub 2020 Apr 16.

Department of Neurosurgery, The Second Affiliated Hospital of Zhejiang University School of Medicine, Hangzhou, China.

Meningiomas are primary intracranial tumors derived from arachnoid cap cells or meningothelial cells and usually display dural attachment. However, a small proportion of meningiomas that arise from the Sylvian fissure do not manifest dural attachment. Sylvian fissure meningiomas are relatively rare and have differential characteristics as compared with typical meningiomas. Read More
