Meningioma Treatment: Observation, Surgery & Radiosurgery
Meningiomas are the most common primary brain tumor. They grow from the lining of the brain (the meninges) and are usually benign and slow-growing. Many are found incidentally on scans done for another reason.
The key question is not “is it a tumor?” but “does it need treatment?” Size, location, growth over time, and whether it is causing symptoms all matter. Dr. Daggubati sees many patients who simply need reassurance and a follow-up MRI — and others whose tumor is best removed through a small, targeted opening.
Symptoms
- Often none — found incidentally
- Headaches
- Seizures
- Vision or hearing changes depending on location
- Weakness or numbness from pressure on the brain
How it is diagnosed
MRI with contrast shows a characteristic appearance. A CT may be added to look at the adjacent skull. Serial imaging over 6–12 months establishes whether a tumor is growing.
Treatment options
Without surgery
Observation with interval MRI for small, asymptomatic tumors. Stereotactic radiosurgery for small tumors in hard-to-reach locations or in patients who prefer to avoid surgery.
Surgical options Dr. Daggubati offers
- Keyhole / minimally invasive craniotomy for convexity and parasagittal meningiomas
- Endoscopic skull base approaches for meningiomas at the base of the skull
- Radiosurgery for residual or recurrent tumor
Common questions
My meningioma was found by accident. Do I need surgery?
Often not. Small tumors without symptoms are typically followed with a repeat MRI. Surgery is recommended when a tumor grows, causes symptoms, or sits where growth would become dangerous.
Is a meningioma cancer?
The large majority (about 80–90%) are WHO grade 1, meaning benign. Grade 2 and 3 tumors are less common and may need radiation after surgery.
Not sure this is you?
Bring your imaging and your story. A single visit usually clarifies what is going on and which options are realistic. Request an appointment or call (301) 718-9611.
