Lesions may be classified by the shape they form, as is the case with many ulcers, which can have a bullseye or 'target' appearance.

Definition Usually, a brain lesion is an incidental finding unrelated to the condition or symptom that led to the imaging test in the first place. A brain lesion may involve small to large areas of your brain, and the severity of the underlying condition may range from relatively minor to life-threatening.

- deep lesioning is when a small target area in destroyed in the brain's interior. The appeal though of deep lesioning is that it can serve as a remedy for very specific disorders.Deep Lessioning is the insertion of a thin, insulated wire into the brain through which an electrical current is sent that destroys the brain cells at the tip of the wire.

Brain Tumor A brain tumor is a collection, or mass, of abnormal cells in your brain. Your skull, which encloses your brain, is very rigid. Any growth inside such a restricted space can cause problems. Brain tumors can be cancerous (malignant) or noncancerous (benign). When benign or malignant tumors grow, they can cause the pressure inside your skull to increase.

lesion [le´zhun] any pathological or traumatic discontinuity of tissue or loss of function of a part. Lesion is a broad term, including wounds, sores, ulcers, tumors, cataracts, and any other tissue damage. They range from the skin sores associated with eczema to the changes in lung tissue that occur in tuberculosis.

Brain Lesions (Lesions on the Brain) Immune: The individual's immune system mistakenly attacks and attempts to destroy brain tissue components, such as myelin (a sheath surrounding nerve cells). The resulting scar tissue can be seen in multiple sclerosis, for example. These types of lesions usually progress in development over years.

Lesion There is no designated classification or naming convention for lesions. Because the definition of a lesion is so broad, the varieties of lesions are virtually endless. Although most frequently found in the mouth, on the skin, and in the brain, or anywhere where a tumor may occur, [citation needed] lesions can occur anywhere in the body that comprises soft tissue or osseous matter.

Brain Lesions (Lesions on the Brain) Brain Lesions Causes. From the above description of brain lesion types, it is evident that the different types are arranged, in general, according to different mechanisms that lead to brain cell changes which produce various brain lesions. The causes, however, can be further categorized. Trauma: penetrating or blunt.
