1 Brain lesions (lesions on the brain) refers to any type of abnormal tissue in or on brain tissue.  Major types of brain lesions are traumatic, infectious, malignant, benign, vascular, genetic, immune, plaques, brain cell death or malfunction, and ionizing radiation.
Often, a brain lesion has a characteristic appearance that will help your doctor determine its cause. Sometimes the cause of the abnormal-appearing area cannot be diagnosed by the image alone, and additional tests or follow-up tests may be necessary. Among the known possible causes of brain lesions are: Brain aneurysm. Brain AVM (arteriovenous malformation) Brain tumor (both cancerous and noncancerous) Encephalitis. Hydrocephalus (a congenital brain abnormality) Multiple sclerosis.
