What is a common site of Tuberculosis infection besides the lungs?

Tuberculosis (TB) is primarily known as a respiratory disease affecting the lungs; however, it can also affect other parts of the body. The kidneys are a common extrapulmonary site for TB infection. When the bacteria that cause TB enter the bloodstream, they can spread and infect various organs, including the kidneys. Tuberculous kidney infection can lead to significant health issues, including abscess formation and can also affect kidney function.

In the context of other choices, while TB can theoretically affect the heart, skin, or eyes, these areas are much less common for infection when compared to the kidneys. Cardiac involvement is rare and often occurs in the context of disseminated disease. Skin manifestations of TB can occur, but again, these are not the primary sites of infection. Eye infections due to TB, such as uveitis, are possible but are also very uncommon compared to the incidence of renal TB. Therefore, the kidneys represent a significant and recognized location for tuberculosis infection outside the pulmonary system.
