Structural lesions refer to abnormal physical changes in the body's tissues or organs, often caused by injury, disease, or congenital abnormalities. These changes can be seen through medical imaging techniques such as X-rays, CT scans, or MRIs. Structural lesions can affect the function of the affected tissue or organ, leading to symptoms and health problems. Treatment for structural lesions may involve surgery, medication, or other interventions to address the underlying cause and improve the patient's health. **

Lesions in the brain can be caused by a variety of factors, including traumatic brain injury, infections, tumors, stroke, and autoimmune diseases. Traumatic brain injury can result in physical damage to the brain tissue, while infections such as meningitis or encephalitis can lead to inflammation and damage. Tumors can also cause lesions by disrupting the normal structure of the brain, and strokes can result in areas of dead tissue due to lack of blood flow. Autoimmune diseases like multiple sclerosis can cause the immune system to attack the brain, leading to the formation of lesions. **
