Infiltrative pneumonic form are active forms of pulmonary tuberculosis. Inflammatory changes in the form of rounded focus, called infiltration (see), often located in subclavian area. Infiltration is a pneumonic hearth with caseous centre and therefore inclined to the formation of cavities, bronchogenic and lymphogenous distribution (Fig. 4); sometimes the process captures whole lobe of the lung (pleural lobit; Fig. 5).
To infiltrative pneumonic processes is also caseous pneumonia is a severe form of tuberculosis, which is now rare.
The differential diagnosis with pneumonia non-tubercular etiology of key importance thorough search of Mycobacterium tuberculosis in the respiratory secretions, and tuberculin skin test, which when nonspecific lung diseases, is negative. Only in severe forms of caseous pneumonia due anergy tuberculin skin test also may be negative.
All infiltrative pneumonic form of TB require treatment in hospital. When properly administered chemotherapy disappearing mycobacteria and resorption of pneumonic changes; the small cavernous usually remain fibrotic scars, especially evident after caseous pneumonia.
