A common characteristic of tuberculosis (TB) in immunocompromised individuals is the tendency for the disease to present without cavitation. In healthy individuals, TB often leads to cavitary lung lesions, which are areas of lung tissue that have been destroyed by the infection. However, in those with weakened immune systems, such as individuals with HIV/AIDS or those on immunosuppressive therapy, the immune response is inadequate to contain the infection effectively. As a result, TB may not exhibit the typical cavitary lesions seen in immunocompetent hosts and may manifest as more diffuse or miliary disease instead.

This altered presentation is significant because it can impact diagnosis and treatment strategies. Without the cavitary lesions, clinicians may need to rely more on imaging studies and other laboratory tests to confirm the presence of TB. Consequently, recognizing this characteristic can lead to more timely and appropriate management of TB in immunocompromised patients.
