Repeatability of Magnetic Resonance Elastography‐Derived Mechanical Parameters in Intracranial Meningiomas

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Magnetic resonance elastography (MRE) quantifies tissue viscoelasticity, offering insights into intracranial meningiomas. MRE‐derived parameters, including the storage modulus (G') and the magnitude of the complex modulus (|G*|), may aid neurosurgical planning, but their repeatability remains unexplored in brain tumors.

Recommendations on the management of meningioma and sex hormone therapy: The results of a collaborative effort between neurosurgical, endocrine and gynecological societies

Brain and Spine
Introduction: Exogenous and endogenous sex hormones, especially Progesterone agonists, may be causally linked to meningioma progression. Cessation of treatment leads to stabilization or regression of Progestin-induced meningioma.

Modeling NF2 with human arachnoidal and meningioma cell culture systems: NF2 silencing reflects the benign character of tumor growth

Neurobiology of Disease, 2008
Meningiomas, common tumors arising from arachnoidal cells of the meninges, may occur sporadically, or in association with the inherited disorder, neurofibromatosis 2 (NF2).

Chemotherapy for meningiomas

Journal of Neuro-Oncology, 1996
The most efficacious treatment for meningiomas is surgery. For incompletely resected or recurrent tumors, radiotherapy can be given. However, when the meningioma is unresectable and/or all other previous treatments have failed, immunotherapy or chemotherapy may be considered for malignant tumors and immunotherapy and hormone therapy may be considered ...

Alzheimer disease genetic risk factor APOE e4, and cognitive abilities in 111,739 UK Biobank participants [PDF]

, 2016
Background: the apolipoprotein (APOE) e4 locus is a genetic risk factor for dementia. Carriers of the e4 allele may be more vulnerable to conditions that are independent risk factors for cognitive decline, such as cardiometabolic diseases.

Nasal Branch of the Anterior Ethmoidal Artery and Cribroethmoidal Groove: New Frontal Sinus Landmarks

The Laryngoscope, EarlyView.
This study investigates the nasal branch of the anterior ethmoidal artery (NbAEA) and the cribroethmoidal groove (CrEGr) as novel and reliable anatomical landmarks for expanded endoscopic frontal sinusotomies. Through cadaveric dissections and a clinical case series, both structures were consistently identified and shown to aid safe and accurate ...

Surgical Management of a Cerebellopontine Angle Tumor After Sudden Onset Facial Paralysis

The Laryngoscope, EarlyView.
Patients with cerebellopontine angle tumors rarely experience acute facial weakness. In this report, we summarize a case where immediate tumor decompression after a patient presented with sudden ipsilateral flaccid facial palsy resulted in complete recovery of facial nerve function, followed by staged gross total tumor resection. Return of facial nerve

Multiple meningiomas consisting of fibrous meningioma, transitional meningioma, and meningotheliomatous meningioma in one adult patient

Asian Journal of Neurosurgery, 2015
Multiple histopathology of meningioma is a condition in which the patient has more than one histopathology feature of meningioma in different intracranial locations, with or without sign of neurofibromatosis. Meningiomas are the most common, non-glial, primitive intracranial tumors; their prevalence among operated tumors is around 13-19%.

Metastatic meningioma presenting as cancer of unknown primary

Rare Tumors, 2013
We describe a case of anaplastic meningioma presenting in an extracranial osseous location, initially diagnosed as cancer of unknown primary. Although anaplastic meningioma comprise 3% of all meningiomas, this subtype is more likely to be associated with
