Background: The aetiology of meningiomas is largely unknown although hormones have been suggested to play a role.
Methods: A cohort study was performed to evaluate hormone-related factors associated with meningioma. Patients (12-89 years) with a first diagnosis of meningioma (January 1996-June 2008) were identified from The Health Improvement Network UK primary care database and age- and sex-matched to controls (n=10000) from the same cohort. Odds ratios (ORs) were calculated following a nested case control analysis using unconditional logistic regression.
Results: In total, 745 patients with meningioma were identified from a study population of 2171287. No significantly increased risk of meningioma was found among female users of oral contraceptives (OR: 1.15; CI: 0.67-1.98), hormone replacement therapy (OR: 0.99; CI: 0.73-1.35) or low-dose cyproterone acetate (CPA; OR: 1.51; CI: 0.33-6.86) compared with non-users. There was a significantly increased risk of meningioma among male users of androgen analogues (OR: 19.09; CI: 2.81-129.74) and among users of high-dose CPA (OR: 6.30; CI: 1.37-28.94) compared with non-users, however there were only three cases currently using these drugs. No significant association was found between meningioma and prostate, breast, or genital cancers.
Conclusions: Our results do not support a role for exogenous hormone use by females in meningioma development. The risk in males was only observed with high-dose, short-term (<1 year) therapy.
Impact: While hormonal cancers and therapies are not associated with meningioma in females, the risk in males requires further investigation.

Objectives: To evaluate post-operative semicircular canal function in patients with non-vestibular schwannoma (VS) cerebellopontine angle (CPA) tumors by video Head Impulse Test (vHIT).
Methods: Fourteen patients with non-VS CPA tumors who underwent surgery. The gain in vestibulo-ocular reflex (VOR) was examined pre- and post-operatively for the semicircular canals in patients with non-VS CPA tumors.

Sphenoid wing meningiomas (SWM) frequently compress structures of the optic pathway, resulting in significant visual dysfunction characterized by vision loss and visual field deficits, which profoundly impact patients' quality of life (QoL), daily activities, and independence. The objective of this study was to assess the impact of SWM surgery on patient-reported outcome measures (PROMs) regarding postoperative visual function. The Visual Function Score Questionnaire (VFQ-25) is a validated tool designed to assess the impact of visual impairment on quality of life.

Background/objectives: Brain tumor classification is a crucial task in medical diagnostics, as early and accurate detection can significantly improve patient outcomes. This study investigates the effectiveness of pre-trained deep learning models in classifying brain MRI images into four categories: Glioma, Meningioma, Pituitary, and No Tumor, aiming to enhance the diagnostic process through automation.
Methods: A publicly available Brain Tumor MRI dataset containing 7023 images was used in this research.

: With the rise in prevalence of diagnostic genetic techniques like RNA sequencing and whole exome sequencing (WES), as well as biological treatment regiments for cancer therapy, several genes have been implicated in carcinogenesis. This review aims to update our understanding of the Neurofibromatosis 2 (NF2) gene and its role in the pathogenesis of various cancers. : A comprehensive search of five online databases yielded 43 studies that highlighted the effect of sporadic NF2 mutations on several cancers, including sporadic meningioma, ependymoma, schwannoma, mesothelioma, breast cancer, hepatocellular carcinoma, prostate cancer, glioblastoma, thyroid cancer, and melanoma.

Skull base tumors such as meningiomas and schwannomas are often pathologically benign. However, surgery for these tumors poses significant challenges because of their proximity to critical structures such as the brainstem, cerebral arteries, veins, and cranial nerves. These structures are compressed or encased by the tumor as they grow, increasing the risk of unintended injury to these structures, which can potentially lead to severe neurological deficits.
