Summary
Electroencephalogram (EEG) effectively detects abnormalities in most meningioma cases, proving valuable for supplementary diagnosis. While precise location accuracy varies, EEG significantly aids in identifying intracranial meningiomas.
Area of Science:
- Neurology
- Neurosurgery
- Diagnostic Imaging
Context:
- Meningiomas are primary intracranial tumors.
- Accurate diagnosis and localization are crucial for effective treatment planning.
- Electroencephalography (EEG) is a non-invasive neurophysiological monitoring technique.
Purpose:
- To evaluate the diagnostic value of EEG in identifying intracranial meningiomas.
- To assess the accuracy of EEG in lesion-location and lesion-side determination.
- To determine the utility of EEG as a supplementary diagnostic tool for meningiomas.
Summary:
- Investigated 42 surgically and pathologically confirmed meningioma cases using EEG.
- EEG revealed abnormalities in 95.24% of cases.
- Achieved a 64.29% accuracy for lesion location, 26.19% for lesion side, and 90.48% for combined location and side accuracy.
Impact:
- EEG demonstrates high abnormality detection rates in meningioma patients.
- EEG serves as an important supplementary diagnostic method for intracranial meningiomas.
- Findings support the continued use of EEG in the diagnostic workup of suspected meningiomas.
