Meningioma diagnosis typically involves a combination of methods:
- Medical History and Physical Examination: A thorough medical history and neurological examination to assess symptoms such as headaches, vision problems, or neurological deficits.
- Imaging Studies:
- Magnetic Resonance Imaging (MRI): The preferred imaging technique to visualize the meningioma. An MRI provides detailed images of the brain and spinal cord and can help determine the tumor's size, location, and characteristics.
- Computed Tomography (CT) Scan: Often used when MRI is not available or contraindicated. It helps in assessing bone involvement and calcification within the tumor.
- Advanced Imaging Techniques:
- MRI with Contrast (Gadolinium): Enhances the visibility of the tumor and distinguishes it from surrounding tissues.
- Functional MRI (fMRI): Used to map brain functions and assess the relationship between the tumor and critical brain areas.
- Positron Emission Tomography (PET) Scan: Sometimes used to assess the tumor's metabolic activity.
- Biopsy: In some cases, a biopsy may be performed to obtain a tissue sample for histological examination. This can confirm the diagnosis and provide information on the tumor's grade and potential aggressiveness.
Diagnosis is a multi-step process involving various GW Cancer Center neuro-oncology specialists, including neurologists, radiologists, and neurosurgeons, to ensure accurate identification and appropriate, personalized treatment planning. Regular follow-up and monitoring by your GW Cancer Center multidisciplinary team are essential to assess the treatment's effectiveness and manage any side effects or complications.
