Meningioma is the most common tumor of the central nervous system, most of which is benign. Even after complete resection, a high rate of recurrence of meningioma is observed. From in-depth study of its pathogenesis, it has been found that a number of chromosomal variations and abnormal molecular signals are closely related to the occurrence and development of malignancy in meningioma, which may provide the theoretical basis and potential direction for accurate and targeted treatment. We have reviewed advances in chromosomal variations and molecular mechanisms involved in the progression of meningioma, and have highlighted the association with malignant biological behavior including cell proliferation, angiogenesis, increased invasiveness, and inhibition of apoptosis. In addition, the chemotherapy of meningioma is summarized and discussed.

Background: Meningioma en plaque (MEP) is a rare subtype of meningioma with a carpet-like growth pattern, often causing hyperostosis. Even rarer is the presentation of bilateral MEP posing diagnostic and therapeutic challenges. Management of MEP usually entails early complete resection.

While World Health Organization (WHO) grade I meningiomas are typically slow growing and associated with favorable prognoses, a subset may exhibit unexpectedly aggressive behavior and resistance to conventional treatment approaches. Recurrent grade I meningiomas, in particular, are associated with a poorer prognosis despite their benign histological classification, underscoring the need for advanced genomic and radiomic analyses to refine diagnostic accuracy. We present a case of a 52-year-old female with a grade I parafalcine meningioma initially deemed nonaggressive, but ultimately recurred multiple times over several years despite undergoing repeated craniotomies and several courses of radiosurgery.

Background: Preoperative embolization is hypothesized to reduce blood loss and operative time for meningioma resection, but the impact of preoperative embolization on long-term oncological outcomes and molecular features of meningiomas is incompletely understood. Here we investigate how preoperative embolization influences perioperative and long-term outcomes and molecular features of atypical WHO grade 2 meningiomas.
Methods: Patients who underwent resection of WHO grade 2 meningiomas from 1997 to 2021 were retrospectively identified from an institutional database.

The use of theragnostics in nuclear medicine has significantly advanced, particularly peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors. Meningiomas often overexpress somatostatin receptors (SSTR), making them potential candidates for PRRT. However, the lack of large-scale standardized trials limits its clinical application.

Objective: The aim of this study was to investigate the relationship between the clinical and radiological characteristics of olfactory groove meningiomas (OGMs) and their molecular profiles.
Methods: The authors performed targeted next-generation and whole-genome sequencing in 123 OGM samples collected from 4 international institutions, focusing on known meningioma-driver genes. They compared the molecular data with the clinical and radiographic features of the tumors.
