Multiple meningiomas evaluated by computed tomography
Abstract:
There were 15 cases of multiple meningiomas in a consecutive series of 168 cases of meningioma studied by computed tomography during the last 5 years. This incidence of 8.9% is significantly higher than the 1 to 3% incidence reported previously. A brief clinical survey of the 15 cases and a description of the location of the meningiomas as demonstrated by computed tomography are presented. The possible cause of the higher incidence and various theories of the etiology of multiple meningiomas are explored.
Insights
Computed tomography revealed a higher incidence of multiple meningiomas (8.9%) than previously reported. This study explores potential causes and etiological theories for this increased occurrence.
Area of Science:
- Neurology
- Neurosurgery
- Radiology
Background:
- Multiple meningiomas are rare tumors.
- Previous incidence rates for multiple meningiomas range from 1-3%.
Purpose of the Study:
- To report a higher observed incidence of multiple meningiomas.
- To describe the clinical and radiological features of these cases.
- To explore potential etiologies for multiple meningiomas.
Main Methods:
- Retrospective analysis of 168 meningioma cases over 5 years.
- Utilized computed tomography (CT) for diagnosis and characterization.
- Clinical data and tumor locations were documented.
Main Results:
- Identified 15 cases of multiple meningiomas, an incidence of 8.9%.
- This incidence is significantly higher than previously reported figures.
- Clinical and CT findings for the 15 cases are presented.
Conclusions:
- The incidence of multiple meningiomas may be increasing.
- Further research is needed to understand the etiology of multiple meningiomas.
- Computed tomography plays a crucial role in diagnosing multiple meningiomas.
