Lesions

Abnormal tissues (lesions) in the brain can take various forms.

All brain lesions are caused by damage or injury to the brain, but the lesions themselves have a variety of characteristics that make them challenging to catalog.

Some types may include:

  • Abscess: An abscess is an area of infection and can include inflamed tissue and pus.
  • Arteriovenous malformations (AVM): This type of brain lesion occurs when blood vessels in the brain grow in a tangle and can leak blood into the brain or compress the brain.
  • Cerebral Infarction: An infarction is a medical term for the death of tissue. A cerebral infarction is also referred to as a stroke and is a lesion in the brain that consists of a group of cells that died.
  • Multiple Sclerosis (MS): MS is a condition in which the body damages the brain and spinal cord. The lesions that result from this damage make it hard for messages to be sent from the brain to the rest of the body.
  • Tumors: Tumors are groups of cells that grow abnormally. Some tumors in the brain are noncancerous, or benign. Others are cancerous. Tumors may grow quickly or they may remain stable.

The key to treating brain lesions is to remove or destroy them while protecting the healthy parts of the brain. If healthy brain tissue is damaged it could impair a person’s motion, senses, or language and memory.

Your doctor will be your best source of information on treatment options for your lesion.
