What does a calcified meningioma mean?
If calcification is present in a small meningioma, this signifies slow or absent tumor growth prompting the need to closely monitor the lesion without immediate surgical intervention [6-7].
Do calcified meningiomas enhance?
After contrast administration, meningiomas typically demonstrate avid, homogeneous enhancement (Fig. 5a); however, they may occasionally have areas of central necrosis or calcification that do not enhance. Calcification is typically best demonstrated on CT, with variable reported rates of occurrence.
How big does a meningioma have to be for surgery?
Ideally, surgical removal of meningioma entails removal of a one-centimeter margin all the way around the tumor. However, this type of resection is not always possible, especially in the skull base. These deep-seated tumors in the skull base require referral to a skull base neurosurgeon.
How is calcified meningioma treated?
Medications may be used to relieve some of the side effects of meningiomas. These include steroids to reduce swelling and edema around the tumor, and anticonvulsants to prevent or control seizures. If a meningioma is causing symptoms or is growing in size, surgical removal is often recommended.
How long does it take a tumor to calcify?
The median interval from treatment to the first appearance of tumor calcification was 2.0 months (95% confidence interval: 1.2–8.8 months).
What does it mean when a tumor is calcified?
Calcification happens when tumours are no longer able to regulate the movement of calcium in and out of their cells. This may be due to damage to the blood vessels, resulting in a localised haemorrhage (uncontrolled blood flow) within the tumour that kills some of the cells.
Can a meningioma cause sinus problems?

What is the prognosis of a patient with a frontal lobe tumor?
The presence of a frontal lobe tumor may only cause personality changes, and may not be life-threatening. One important factor that affects brain tumor prognosis is the type of tumor present. The size of a tumor at the time of diagnosis affects a patient’s brain tumor prognosis.
Why do tumors calcify?
Brain calcification may be triggered by a variety of medical problems. It may be associated with stroke or brain injury, or it may occur in tumors in the brain. Hypoparathyroidism, in which levels of parathyroid hormone in the body are abnormally low, may also be associated with calcification.
What is a calcified meningioma?
