Ghon's complex is a lesion seen in the lung that is caused by tuberculosis. [1] [2] The lesions consist of a Ghon focus along with pulmonary lymphadenopathy within a nearby pulmonary lymph node. A Ghon's complex retains viable bacteria, making them sources of long-term infection, which may reactivate and trigger secondary tuberculosis later in ...
Tuberculosis usually affects the lungs, but it spread to the brain, spine, and kidneys. Not everyone infected with the bacteria that causes TB will get sick, which is called a latent or inactive ...

M. tuberculosis also has the potential of spreading to other parts of the body. This can cause blood in urine if the kidneys are affected ...
Mycobacterium tuberculosis is the most common cause of both pulmonary tuberculosis and tuberculous lymphadenitis. [1] [6] Historically, transmission of Mycobacterium bovis from dairy consumption was another frequent cause of tuberculous lymphadenitis, but incidence has drastically decreased in developed countries since the advent of pasteurization and other efforts to prevent bovine ...
The most common cause of a single lung cavity is lung cancer. [4] Bacterial, mycobacterial, and fungal infections are common causes of lung cavities. [5] Globally, tuberculosis is likely the most common infectious cause of lung cavities. [6] Less commonly, parasitic infections can cause cavities. [5] Viral infections almost never cause cavities ...
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. [21]
