Aspergilloma in an old tuberculosis cavity; healed, calcified tuberculous lesions are also present towards the right of the image Healed tuberculous cavity, where the entire left lung is destroyed. Post-tuberculosis lung disease (PTLD) is ongoing lung disease that is caused by tuberculosis (TB) but persists after the infection is cured. [1]
Tuberculosis has been known by many names from the technical to the familiar. [202] Phthisis (φθίσις) is the Greek word for consumption, an old term for pulmonary tuberculosis; [7] around 460 BCE, Hippocrates described phthisis as a disease of dry seasons.

It is possible that, following an initial tuberculosis infection resulting in bacteremia, a foci of granulomatous inflammation may coalesce into a caseous tuberculoma. [20] Pulmonary tuberculomas may arise due to repeated cycles of necrosis and re-encapsulation of foci, or, alternatively, the shrinkage and fusion of encapsulated densities.
There were positive results in tuberculosis therapy following plombage in the decades of the 1930s, 1940s and early-1950s. However, with the introduction of drugs which were effective in destroying the tuberculosis bacterium (Mycobacterium tuberculosis), plombage treatment fell into disfavor. In addition, complications of plombage began to ...
Persons with HIV and latent tuberculosis have a 10% chance of developing active tuberculosis every year. "HIV infection is the greatest known risk factor for the progression of latent M. tuberculosis infection to active TB. In many African countries, 30–60% of all new TB cases occur in people with HIV, and TB is the leading cause of death ...
