In fact, death from tuberculosis was greater in diabetic patients. [9] 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 ...
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]
The main chest X-ray findings that can suggest inactive TB are: [2] 1. Discrete fibrotic scar or linear opacity—Discrete linear or reticular densities within the lung. The edges of these densities should be distinct and there should be no suggestion of airspace opacification or haziness between or surrounding these densities.
Tuberculosis patients, both active and inactive, are treated with antibiotics. Treatment typically involves taking multiple antibiotics every day over a period of four to nine months, per the CDC .
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]
M. tuberculosis is able to reproduce inside the macrophage and will eventually kill the immune cell. The primary site of infection in the lungs, known as the Ghon focus, is generally located in either the upper part of the lower lobe, or the lower part of the upper lobe. [13] Tuberculosis of the lungs may also occur via infection from the blood ...
The medical history includes obtaining the symptoms of pulmonary TB: productive, prolonged cough of three or more weeks, chest pain, and hemoptysis.Systemic symptoms include low grade remittent fever, chills, night sweats, appetite loss, weight loss, easy fatiguability, and production of sputum that starts out mucoid but changes to purulent.

Worldwide in 2015, the most common causes of cancer death were lung cancer (1.6 million deaths), liver cancer (745,000 deaths), and stomach cancer (723,000 deaths). [7] Lung cancer is largely due to non-infectious causes, such as tobacco smoke. However, liver and stomach cancer are primarily due to infectious causes.
