Meningioma

Introduction

A meningioma is a tumor that arises from the meninges - the membranes that surround your brain and spinal cord. Meningiomas are mostly benign but can be atypical or rarely malignant. They represent about 20% of all tumors in the brain and about 10% of al spinal tumors.

The cause of development of this tumor is not clear. Genetic and environmental factors may be responsible in some patients. Certain risk factors include radiation to the head, female hormones or a genetic abnormality called neurofibromatosis type 2.

Symptoms

Depend mainly on the site of the tumor within the brain or spine. Sign and symptoms include.

1. Gradually progressing headache
2. Seizure
3. Blurring of vision or diplopia
4. Decline in hearing or facial pain
5. Weakness in limbs
6. Decline in memory

Investigations

Meningioma can be diagnosed on Computed Tomography or MRI scans with contrast.

These scans provide information about the location, size of tumor and any bony infiltration. Dural tail sign is a common finding in such tumors.

Treatment

There are basically three options which can be considered.

1. Observation - A meningioma that causes no significant signs and symptoms may be monitored over time.However the size, location rate of growth and age are also some important considerations.

2. Surgical Excision - Most often symptomatic tumors are excised surgically. Dr Asheesh Tandon and his team has extensive experience in removing such tumors through key hole or minimally invasive approach.The goal of the surgery is to remove the tumor completely without causing any fresh neurological deficit.

3. Radiation - Either conventional radiation or Steriotactic radiation therapy is suggested for inaccessible tumors or in residual tumor remnants. Elderly who cannot undergo the surgery may also be considered for radiation therapy to slow down the growth of the tumor.
