[Role of computerized tomography in the diagnosis of cirrhotic pulmonary tuberculosis].
Computed tomography (CT) revealed cirrhotic tuberculosis in 52 patients. In most patients, cirrhosis resulted from infiltrative and fibrocavernous tuberculosis, less frequently from tuberculous bronchoadenitis, disseminated and focal tuberculosis, caseous pneumonia. Segmental cirrhosis was present in 15 patients, multisegmental and lobar cirrhosis in 19, and bilateral lung cirrhosis in 2. In 8 patients, pulmonary cirrhosis was accompanied by tuberculous empyema; in 8 more patients lobar cirrhosis was the metatuberculous syndrome of fibrocavernous tuberculosis. Evaluation of the diagnostic potentialities of CT in cirrhotic pulmonary tuberculosis revealed that the major CT semiotics of this clinical type was identical to the basic skialogic signs of routine X-ray study. However, unlike the latter that assesses mainly indirect X-ray signs of the cirrhotic transformation of lung tissue, such as reduced lung volumes, chest deformity, CT objectively detects morphological changes in cirrhosis, the presence and magnitude of specific and metatuberculous changes, interprets clinical and X-ray variants of this form of tuberculosis and its related pulmonary vascular alterations.
