A tuberculoma is a clinical manifestation of tuberculosis which conglomerates tubercles into a firm lump, and so can mimic cancer tumors of many types in medical imaging studies. [1] [2] They often arise within individuals in whom a primary tuberculosis infection is not well controlled. [3]
If there is any question of active TB, sputum smears must be obtained. Therefore, any applicant might have findings grouped in this category, but still have active TB as suggested by the presence of signs or symptoms of TB, or sputum smears positive for AFB.

The Mantoux tuberculin skin test is often used to screen people at high risk for TB. [100] Those who have been previously immunized with the Bacille Calmette-Guerin vaccine may have a false-positive test result. [107] The test may be falsely negative in those with sarcoidosis, Hodgkin's lymphoma, malnutrition, and most notably, active ...
Possible harms from the screening test: for example, X-ray images involve exposure to potentially harmful ionizing radiation; The likelihood of the test correctly identifying cancer; The likelihood that cancer is present: Screening is not normally useful for rare cancers. Possible harms from follow-up procedures; Whether suitable treatment is ...
Tuberculosis cases ticked up from 2020 to 2022. That's likely a result of reduced access to medical care — and therefore screenings — during the pandemic. Why tuberculosis cases have risen in ...
Some people who have been infected with TB may have a negative reaction when tested years after infection, as the immune system response may gradually wane. This initial skin test, though negative, may stimulate (boost) the body's ability to react to tuberculin in future tests.
