J Pathol Transl Med 2020 Jul 1. Epub 2020 Jul 1.

Department of Neurosurgery, Gil Medical Center, Gachon University College of Medicine, Incheon, Korea.

Meningiomas in bone are rarely subjected to fine-needle aspiration diagnosis, and those arising in the skull bone with a cystic presentation are rare. A 24-year-old woman presented with subdural hemorrhage, and subsequent radiology depicted an osteolytic mass-like lesion in the sphenoid bone. Intraoperatively, a solid and cystic hemorrhagic lesion mimicking an aneurysmal bone cyst was observed in the sphenoid bone with dural tearing. Read More

Middle fossa meningiomas.

Handb Clin Neurol 2020 ;170:65-67

Miami Neuroscience Institute, Baptist Health of South Florida, Miami, FL, United States; Division of Neuroscience, Herbert Wertheim College of Medicine, Florida International University, Miami, FL, United States. Electronic address:

The middle cranial fossa is bounded anteriorly by the sphenoid ridge, medially by the lateral wall of the cavernous sinus and Meckel's cave, posteriorly by the sphenoid wing and petrous bone, and laterally by the greater wing of sphenoid and squamous temporal bone. In normal individuals, unnamed venous channels within the dura and arachnoid granulations can be seen on the floor of this fossa by the operating surgeon. Meningiomas arising mainly from the dura of the floor are uncommon, and middle fossa meningiomas have been arbitrarily named so based on an attachment of more than 75% to this location. Read More

Hyperostosing sphenoid wing meningiomas.

Handb Clin Neurol 2020 ;170:45-63

Department of Neurosurgery, Addenbrooke's Hospital, Cambridge, United Kingdom. Electronic address:

Some sphenoid wing meningiomas are associated with a significant hyperostotic reaction of the adjacent sphenoid ridge that may even exceed the size of the intradural mass. The decision-making process and surgical planning based on neuroanatomic knowledge are the mainstays of management of this group of lesions. Given their natural history and biologic behavior, many hyperostosing meningiomas at this location require long-term management analogous to a chronic disease. Read More

Sphenoid wing meningiomas.

Handb Clin Neurol 2020 ;170:37-43

Miami Neuroscience Institute, Baptist Health of South Florida, Miami, FL, United States; Division of Neuroscience, Herbert Wertheim College of Medicine, Florida International University, Miami, FL, United States.

Meningiomas that arise from the dura along the sphenoid wing can occur in globoid or en plaque forms. Radiographically they can be defined as occurring in the medial, middle, or lateral portions of the sphenoid wing. The medial group carries the highest neurologic risk for surgical treatment, while the hyperostosing en plaque type is the most difficult to remove completely because of orbital and bone involvement.

Asian J Neurosurg 2018 Jul-Sep;13(3):822-825

Department of Neurosurgery, Institute of Human Behavior and Allied Sciences, New Delhi, India.

Intracranial calcifications are not uncommon and are mostly seen with intracerebral hematomas, tuberculomas, and brain tumors. These lesions may be intra- or extra-axial and occasionally pose challenge in the diagnosis. We report a case of multiple intracranial extra-axial calcifications with congenital skull anomaly and multiple meningiomas. Read More

Preoperative embolization of skull base meningiomas: A systematic review.

J Clin Neurosci 2019 Jan 29;59:259-264. Epub 2018 Sep 29.

Department of Neurological Surgery, University of Virginia, Charlottesville, VA, United States.

Neoadjuvant endovascular embolization of skull base meningiomas may facilitate surgical resection, thereby potentially decreasing operative morbidity. However, due to variation in the reported efficacy and complication rates, the utility of embolization remains incompletely defined. The aim of this systematic review is to assess the outcomes of preoperative embolization for skull base meningiomas. Read More

Prognostic factors in the surgical treatment of intracanalicular primary optic nerve sheath meningiomas.

J Neurosurg 2018 09;131(2):481-488

Departments of1Neurosurgery and.

Objective: Although meningiomas frequently involve the optic nerve, primary optic nerve sheath meningiomas (ONSMs) are rare, accounting for only 1% of all meningiomas. Given the high risk of vision loss with these tumors, surgical intervention is seldom considered, and radiation or observation is commonly applied. Here, the authors describe the visual outcomes for a series of patients who were treated with surgery aiming at maximal tumor resection and highlight their prognostic factors. Read More

Mini-Pterional Craniotomy for Resection of Parasellar Meningiomas.

World Neurosurg 2018 Sep 22;117:e637-e644. Epub 2018 Jun 22.

Department of Neurosurgery, University of Oklahoma Health Sciences Center, Oklahoma City, Oklahoma, USA. Electronic address:

Background: Surgical resection of parasellar meningiomas is a challenging operation that traditionally has been performed with a large pterional or orbitozygomatic craniotomy. In this study, we report patient outcomes and detail our surgical approach when resecting these tumors with a smaller, less invasive "mini-pterional" craniotomy.

Methods: We performed a retrospective review on all patients undergoing a mini-pterional craniotomy for resection of parasellar meningiomas from 2012 to 2016. Read More

Malignant Orbital Meningioma Originating from the Frontal Lobe.

Ocul Oncol Pathol 2018 Apr 10;4(3):186-190. Epub 2017 Nov 10.

Gavin Herbert Eye Institute, University of California, Irvine, Irvine, CA, USA.

Purpose Of The Study: Orbital meningiomas are typically benign tumors, most commonly originating from the dura of the sphenoid wing or the optic nerve sheath.

Procedures: We describe an unusual case of a malignant meningioma originating from the frontal lobe that ultimately produced orbital and distant metastases.

Results And Conclusions: Orbital invasion by the meningioma was preceded by multiple incomplete resections, which may have facilitated access to the orbit. Read More

Surgical outcomes after reoperation for recurrent skull base meningiomas.

J Neurosurg 2018 05;130(3):876-883

Departments of1Neurological Surgery and.

Objective: Skull base meningiomas are surgically challenging tumors due to the intricate skull base anatomy and the proximity of cranial nerves and critical cerebral vasculature. Many studies have reported outcomes after primary resection of skull base meningiomas; however, little is known about outcomes after reoperation for recurrent skull base meningiomas. Since reoperation is one treatment option for patients with recurrent meningioma, the authors sought to define the risk profile for reoperation of skull base meningiomas. Read More

Department of Neurosurgery, Brown University, Providence, Rhode Island, USA; Normal Prince Neurosciences Institute, Brown University, Providence, Rhode Island, USA; Warren Alpert Medical School of Brown University, Brown University, Providence, Rhode Island, USA. Electronic address:

Background: The incidence of 2 distinct tumor types occupying the same anatomic location is rarely observed and may be accounted for by 2 separate mechanisms: tumor-to-tumor metastasis and collision tumors, where 2 adjacent tumors invade one another. These rare phenomena arise from distinct mechanisms, which may affect their preoperative recognition, surgical approach, and postoperative care. We review 2 cases, highlighting their identification and perioperative management. Read More

Surgical management of giant sphenoid wing meningiomas encasing major cerebral arteries.

Neurosurg Focus 2018 04;44(4):E12

OBJECTIVE Sphenoid wing meningiomas are a heterogeneous group of tumors with variable surgical risks and prognosis. Those that have grown to a very large size, encasing the major cerebral arteries, are associated with a high risk of stroke. In reviewing the authors' series of giant sphenoid wing meningiomas, the goal was to evaluate how the extent of the tumor's invasion of surrounding structures affected the ability to safely remove the tumor and restore function.

Department of Radiation Oncology, University Hospital of Heidelberg, Im Neuenheimer Feld 400, 69120, Heidelberg, Germany.

Background: Meningiomas of the skull base account for 25-30% of all meningiomas. Due to the complex structure of the cranial base and its close proximity to critical structures, surgery is often associated with substantial morbidity. Treatment options include observation, aggressive surgical intervention, stereotactic or conventional radiotherapy. Read More
