Post-primary TB produces cavities to support massive proliferation of organisms for transmission of infection to new hosts from a person with sufficient immunity to prevent systemic infection. Radiographic manifestations of post-primary tuberculosis overlap with those of primary disease, there are several distinguishing features: Cavitation is an important characteristic of post-primary tuberculosis. Calcified lymph nodes, cavitation, upper lobe fibrocavitary disease suggest miliary dissemination as result of post-primary TB. Chest wall involvement occurring due to direct extension from pulmonary disease manifests as bone and/or cartilage destruction and cutaneous fistula formation. Therefore, most of the resected lung specimens with tuberculosis in a clinical setting are characterized by granulomas and fibrosis rather than endobronchiolar impaction of caseum. tuberculosis; both have distinct characteristics on radiology. It mainly affects the lungs, but it can affect any part of the body, including the tummy (abdomen), glands, bones and nervous system. Most frequently children and young adults are affected (11-30 years of age) and there … The pathology and therefore the radiology of TB infection will be altered based on the efficacy of the immune response and will therefore vary depending on the immune competency. Classically, tuberculosis is classified as primary and post-primary tuberculosis, but the typical radiologic patterns are now complicated by overlapping imaging characteristics as well as occurrence of atypical features seen in immunocompromised children. 21-abr-2017 - Pulmonary manifestations of tuberculosis are varied and depend in part whether the infection is primary or post-primary.

The usual pattern suggestive of post-primary PTB included fibronodular lesions without cavity; patchy heterogeneous consolidation mainly involving segments (S)1, S2 and S6; bronchogenic spreading; and tuberculoma with a range of 0.5 to 4.0 cm in diameter. 2. Emergency Radiology ... they still elected to follow convention, using the classifications of primary and reactivation TB (also referred to as postprimary TB), which have been shown to be inaccurate and confusing. As explained by high oxygen tension and impaired lymphatic drainage, typically there is involvement of: Central airway involvement results in bronchial stenosis which may lead to lobar collapse associated with traction bronchiectasis and mucoid impaction.
