Introduction:
Meningiomas are the most frequent group of intracranial tumours, accounting for around a third of all primary brain tumours. In most cases, they are benign neoplasms that start in the cells of the arachnoid mater and may be located in the intracranial and spinal cavities.
Aim:
To perform a review of the information available on intracranial meningiomas that allows us to update current know-ledge on the subject.
Development:
The review of the literature covers different aspects of intracranial meningiomas, including their epidemiology, histology, risk factors, neurogenetics, diagnostic techniques and prognostic factors.
Conclusions:
Intracranial meningiomas are, today, the leading group of intracranial tumours. Although most of them are histologically benign, recurrence rates range between 10% and 20%, even after performing complete resections. Knowledge of risk factors and the genetic disorders that they present will make it easier in the future to introduce customised treatments to fit each case.
Insights
Meningiomas are common brain tumors, mostly benign but with recurrence rates of 10-20%. Understanding risk factors and genetics can personalize future treatments for intracranial meningiomas.
Area of Science:
- Neuro-oncology
- Neurosurgery
Context:
- Meningiomas represent the most common primary intracranial tumors, constituting approximately one-third of all brain tumors.
- These neoplasms originate from the arachnoid mater cells and can occur within the cranial and spinal cavities.
Purpose:
- To consolidate and update current knowledge on intracranial meningiomas through a comprehensive literature review.
- To provide an updated overview of epidemiology, histology, risk factors, neurogenetics, diagnostic modalities, and prognostic indicators.
Summary:
- Intracranial meningiomas are the leading group of intracranial tumors.
- Despite a predominantly benign histological profile, recurrence rates after complete resection range from 10% to 20%.
- Identifying risk factors and genetic predispositions is crucial for developing tailored therapeutic strategies.
Impact:
- Enhanced understanding of meningioma behavior, including recurrence patterns.
- Facilitates the development of personalized treatment approaches based on individual risk factors and genetic profiles.
- Contributes to improved patient outcomes and management strategies for intracranial meningiomas.
