Incidental Meningiomas
The number of patient imaging studies has increased because of precautious physicians ordering scans when a vague symptom is presented; subsequently, the number of incidental meningiomas detected has increased as…
The Contemporary Role of Stereotactic Radiosurgery in the Treatment of Meningiomas
Meningiomas are among the most common intracranial tumors in adults. The mainstay of treatment has been extirpation. Stereotactic radiosurgery (SRS) is an important option in the management of inaccessible, recurrent,…
Endoscopic Endonasal and Keyhole Surgery for the Management of Skull Base Meningiomas
The resection of anterior skull base meningiomas has traditionally been performed via pterional or unilateral/bilateral subfrontal craniotomies. The supraorbital keyhole approach and the endoscopic endonasal approach, techniques in which the…
Primary Intraosseous Meningioma
Primary intraosseous meningiomas are a subtype of primary extradural meningiomas. They represent approximately two-thirds of extradural meningiomas and fewer than 2% of meningiomas overall. These tumors originate within the bones…
Management of Spinal Meningiomas
Spinal meningiomas are the most common spinal tumors encountered in adults, and account for 6.5% of all craniospinal tumors. The treatment for these lesions is primarily surgical, but emerging modalities…
Secretory Meningiomas
Secretory meningiomas (SM) represent a rare variant of the most common benign intracranial brain tumor. Defined by the histologic appearance of eosinophilic glandular formations and periodic-acidic Schiff–positive pseudopsammoma bodies, SM…
Genomic and Epigenomic Landscape in Meningioma
Meningiomas are the most common primary intracranial neoplasms in adults. Despite their prevalence, their biologic underpinnings remain incompletely described. The recent application of unbiased next-generation sequencing and epigenomic approaches has…
Strategic and Technical Considerations for the Endovascular Embolization of Intracranial Meningiomas
Endovascular embolization is a frequently used adjunct to operative resection of meningiomas. Embolization may decrease intraoperative blood loss, operative time, and surgical difficulty associated with resection. The specific clinical applications…
Predicting Meningioma Consistency on Preoperative Neuroimaging Studies
This article provides an overview of the neuroimaging literature focused on preoperative prediction of meningioma consistency. A validated, noninvasive neuroimaging method to predict tumor consistency can provide valuable information regarding…
Advanced Imaging of Intracranial Meningiomas
Although typically not necessary for the diagnosis of intracranial meningiomas, advanced imaging techniques, including perfusion and diffusion imaging, spectroscopy, and nuclear medicine imaging, can help confirm the diagnosis of intracranial…
