Understanding Lung Lesions Caused by Tuberculosis (TB)

Yes, tuberculosis (TB) can cause lesions in the lungs. TB is a bacterial infection that primarily affects the lungs. When a person with active TB coughs, sneezes, or talks, they release tiny droplets containing the bacteria into the air. These droplets can be inhaled by others, who may then become infected.

In the lungs, the bacteria can cause inflammation and damage to the tissue, leading to the formation of lesions. These lesions can be small and scattered, or they can be large and consolidated, forming cavities. The lesions can cause a variety of symptoms, including cough, fever, weight loss, and fatigue.

In severe cases, TB can spread to other parts of the body, including the kidneys, brain, and bones. It can also cause meningitis, an infection of the membranes that line the brain and spinal cord.
