""" What causes lesions to form on the pancreas? """ This is an example of how we as physicians sometimes fail to do a good job communicating and translating our language to our patients. In this case lesion is a general term that I will explain below. Lesions are simply abnormalities that we have not fully characterized yet, and therefore, cannot identify as anything specific. Lesions can be spots of infection, injury, inflammation, or growths.

lytic infection Lytic infection. Infection of a bacterium by a bacteriophage with subsequent production of more phage particles and lysis, or dissolution, of the cell. The viruses responsible are commonly called virulent phages. Lytic infection is one of the two major bacteriophage-bacterium relationships, the other being lysogenic infection.

Lesions A lesion is any abnormality in the tissue of an organism (in layman's terms, damage), usually caused by disease or trauma. Lesion is derived from the Latin word laesio which means injury.Within psychology the term ablation or brain lesion is used with specific reference to experimentally induced damage or partial removal of animal brains for research purposes.tudies show there is a correlation between lesion in the brain and language, speech, and category-specific disorders. However, lesions in Broca's and Wernicke's areas are not found to alter language comprehension.

Definition MRI showing a brain lesion. A brain lesion is an abnormality seen on a brain-imaging test, such as magnetic resonance imaging (MRI) or a computerized tomography (CT) scan. On CT or MRI scans, brain lesions appear as dark or light spots that don't look like normal brain tissue. 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. Causes.
