Clinical and Radiographic Features of Lymphogenous Dissemination in Pulmonary Tuberculosis

Abstract

At present, the attention of many researchers is focused on the disseminated tuberculosis problem due to its relevance. In some regions of Russia, disseminated tuberculosis is fairly common form of pulmonary tuberculosis. Pulmonary tuberculosis combines processes of different origins, which result from the hematogenous, bronchogenic, and lymphogenous spread of Mycobacterium tuberculosis, which is the reason for a variety of clinical and radiographic manifestations. In particular, the atypical localization of foci in the lower and middle lung segments and the atypical distribution of pulmonary lobular foci frequently lead to diagnostic errors and present problems in their interpretation. This investigation is devoted to the different variants of lymphogenous dissemination of tuberculosis with an emphasis on modern radiodiagnosis.
