1. Clinical presentation and history taking
A detailed symptom timeline is obtained, focusing on headache, seizures, and focal deficits, along with radiation exposure history and family history such as neurofibromatosis.
2. Neurological examination
A comprehensive assessment of consciousness, cranial nerves, and motor and sensory function is performed. Signs such as papilledema and weakness support localization.
3. Computed tomography
CT can demonstrate calcification and cranial bone changes. On non-contrast scans, lesions are typically iso- to hyperdense; contrast enhancement is often homogeneous, enabling an initial assessment of osseous involvement.
4. MRI, non-contrast and contrast-enhanced
MRI is the preferred modality. Contrast enhancement often shows homogeneous enhancement and a “dural tail sign,” and delineates the relationship between the tumor, brain parenchyma, and venous sinuses.
5. Advanced functional MRI techniques
MR spectroscopy and perfusion imaging provide metabolic and perfusion information, assisting evaluation of biological behavior and differentiation between recurrence and necrosis.
6. Histopathological diagnosis and grading
Histopathological evaluation of biopsy or resection specimens is the gold standard. Tumors are graded as WHO grades I–III based on mitotic activity and other criteria.
7. Molecular pathology and emerging biomarkers
Assessment of gene mutations, chromosomal losses, and methylation profiles is increasingly incorporated into grading systems to enable refined risk stratification.
8. Imaging-based differential diagnosis
Differentiation from dural-based entities such as schwannoma, metastasis, and hypertrophic pachymeningitis is required to avoid misdiagnosis.
9. Daily self-check for meningioma
Intracranial tumors cannot be self-detected; however, individuals should remain vigilant for persistent headache, seizures, limb weakness, or visual field/acuity changes and seek medical evaluation promptly.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that delayed diagnosis can lead to ongoing neural compression and irreversible injury. Early, accurate diagnosis is the foundation for optimizing treatment. High-resolution MRI enables detection, and integration with pathology and molecular testing clarifies tumor characteristics, providing precise guidance for individualized surgery, radiotherapy, or surveillance to maximize functional preservation and improve prognosis.
