Tuberculous pleurisy is not classified as pulmonary tuberculosis. Tuberculous pleurisy is a common manifestation of extrapulmonary tuberculosis, often referred to as tuberculosis of the pleura, typically presenting with pleural effusion. Symptoms can sometimes include low-grade fevers in the afternoon and night sweats, which are typical of tuberculosis intoxication. However, the clinical presentation of tuberculous pleurisy can sometimes be atypical, with some patients experiencing high fevers, and there are cases of tuberculous pleurisy without any fever. Additionally, tuberculous pleurisy often coexists with pulmonary tuberculosis. Sometimes, patients with tuberculous pleurisy who undergo a chest CT scan may find lesions in the lungs, but there are also cases where tuberculous pleurisy may exist independently, without the presence of pulmonary tuberculosis.
