Intracranial solid neoplasm-

A brain tumor is an intracranial solid neoplasm, a tumor (defined as an abnormal growth of cells) within the brain or the central spinal canal.

Brain tumors include all tumors inside the cranium or in the central spinal canal. They are created by an abnormal and uncontrolled cell division usually in the brain itself, but also in lymphatic tissue in blood vessels, in the cranial nerves, in the brain envelopes (meninges), skull, pituitary gland or pineal gland.

Within the brain itself the involved cells may be neurons or glial cells (which include astrocytes, oligodendrocytes and ependymal cells). Brain tumors may also spread from cancers primarily located in other organs (metastatic tumors).
