Miliary tuberculosis is a form of tuberculosis that is characterized by a wide dissemination into the human body and by the tiny size of the lesions (1–5 mm). Its name comes from a distinctive pattern seen on a chest radiograph of many tiny spots distributed throughout the lung fields with the appearance similar to millet seeds—thus the term "miliary" tuberculosis.
Management of tuberculosis refers to techniques and procedures utilized for treating tuberculosis (TB), or simply a treatment plan for TB. The medical standard for active TB is a short course treatment involving a combination of isoniazid , rifampicin (also known as Rifampin), pyrazinamide , and ethambutol for the first two months.
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.

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 of the lip, secondary to open pulmonary TB. There is a popular misconception that tuberculosis is purely a disease of the lungs that manifests as coughing. [47] Tuberculosis may infect many organs, even though it most commonly occurs in the lungs (known as pulmonary tuberculosis). [8]
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 ...
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]
Patients with silicosis are particularly susceptible to tuberculosis (TB) infection—known as silicotuberculosis. The reason for the increased risk—3 fold increased incidence—is not well understood. It is thought that silica damages pulmonary macrophages, inhibiting their ability to kill mycobacteria. Even workers with prolonged silica ...
