Overview
Tuberculosis, or TB is a bacterial infection that kills 3 million people worldwide, more people than any other infection in the world. Approximately one-third of the world is infected, and 15 million people in the US. Active tuberculosis kills 60% of the time if not treated, but treatment cures 90% of patients. Most people are infected with TB have latent TB. This means that the bacteria is controlled by the body's immune system. People with latent TB do not have symptoms and cannot transmit TB to other people. However, later if the infected person has a weakened immune system (AIDS, young children, elderly, sick with other diseases, etc.), the bacteria can break out leading to active TB, or TB disease.
Chest Xray findings in pulmonary tuberculosis
- A posterior-anterior chest radiograph is used to detect chest abnormalities. Lesions may appear anywhere in the lungs and may differ in size, shape, density, and cavitation. These abnormalities may suggest TB, but cannot be used to definitively diagnose TB. However, a chest radiograph may be used to rule out the possibility of pulmonary TB in a person who has had a positive reaction to a TST or QFT-G and no symptoms of disease.
- Some common findings of early tuberculosis are:
Infiltration
- It is soft, nodular cotton like fluffy tiny opacities that merge into each other
- Most common location for early lesions are the apico-posterior part (behind the outer borders of clavicle)
Cavity
- Circular, smooth, well defined, thick walled, radiolucent area with no air-fluid levels with surrounding infiltrations.
- Commonly seen in the upper zone
