sequelae of pulmonary tuberculosis radiology

Sequelae of previous tuberculosis that is now inactive manifest characteristically as fibronodular opacities in the apical and upper lung zones. When CD4 counts drop below 200 cells/mm3 then the pattern of infection is more likely to resemble primary infection or miliary tuberculosis 4. When CD4 count drops to below 350 cells/mm3 pulmonary manifestations appear similar to run-of-the-mill post-primary infections (see below). Lippincott Williams & Wilkins.

The primary infection is usually asymptomatic (the majority of cases), although a small number go on to have symptomatic hematological dissemination which may result in miliary tuberculosis. 4. Conventional radiography, Thorax, Respiratory system, Lung. The location of infection within the lung varies with both the stage of infection and age of the patient: Radiographic features depend on the type of infection and are discussed separately. In accordance with the virulence of the organism and the defenses of the host, tuberculosis can occur in the lungs and in extrapulmonary organs. Leung AN. Primary Pulmonary Tuberculosis. The development of an air-fluid level implies communication with the airway, and thus the possibility of contagion. They are usually single (80%) and can measure up to 4 cm in size. Eur J Radiol.
