Brain tumours can be malignant or benign. Malignant brain tumours are fast-growing cancerous growth that originates in the brain and spread to other parts of the brain, including brain cells, meninges (the membrane surrounding the brain), nerve cells, central nervous system and surrounding tissues. Malignant brain tumours can also be secondary brain tumours, which may start in one part of the body including lungs, breast, kidney, skin, or spread, and metastasise to the brain. Benign brain tumours are slow-growing primary brain tumours that are non-cancerous growth with defined borders. These tumours do not spread to the surrounding tissues or organs, and they rarely develop into metastatic tumours.

The skull forms our face and the skull base is composed of different openings through which the spinal cord, blood vessels, and nerves enter or come out of the brain. Brain rest on skull base.

A skull base surgery is a highly advanced approach recommended for diagnosing and removing:
Cancerous or non-cancerous tumours
Any abnormalities in the base of the skull.
Cysts
Congenital anomalies
Congenital malformations.

A cerebral aneurysm/intracranial aneurysm/brain aneurysm is a bulging of the weakened spot in the artery wall in the brain. This weak spot in the wall of the artery widens due to blood flow in the arteries and may rupture due to high blood pressure. An aneurysm can occur anywhere in the artery but mostly is seen in the front portion of the brain which supplies oxygen-rich blood to the brain.

A stroke is an emergency which occurs when either the blood flow to your brain is interrupted, preventing it from getting oxygen and nutrients, causing the death of the brain cells or due to rupture of blood vessels inside the brain leading to brain haemorrhage. Signs and symptoms of a brain stroke include:

Trouble in speaking
Confusion
Paralysis on one side of your body
Vision problems including blurred vision, blackened vision, double vision etc.

Surgery is done to remove tumors in the spinal region. The most common tumor encounter is metastasis and it causes vertebral bone damage or spinal cord or nerve compression. The aim of surgery in such cases is to decompress the spinal cord adequately so that neurology recovers and to provide strength to the spine column by inserting pedicle screws and rods. At the same time specimen can be sent for histopathological and immunohistochemistry markers study, which help in identifying the primary source of the tumor and to start the chemotherapy or radiotherapy accordingly.

This is a procedure performed to correct a congenital disorder known as AVM, where there is a formation of tangled arteries and veins which can lead to seizures, internal bleeding and neurological symptoms. It is possible to have an AVM without any adverse effects, but it is considered to be better to remove the risk through surgery. AVM's can form in the spinal cord, brain, and brainstem, and are revealed using special neuroradiological scans.
