Chronic granulomatous inflammation on histopathology and response to anti-tuberculous treatment was taken as reference standard for diagnosis of tuberculous pleurisy.<\/jats:p>\n                  <jats:p>Results\u2002A total of 249 patients were included in the study, out of which 168 had effusion secondary to tuberculosis. Sago-like nodules visualized on thoracoscopy had a sensitivity of 58.9\u200a%, specificity of 92.6\u200a% and diagnostic accuracy of 69.88\u200a% for pleural tuberculosis. There is a strong association between the presence of sago-like nodules and detection of mycobacterium tuberculosis on Xpert MTB\/Rif assay and AFB culture of pleura (p-value 0.007).<\/jats:p>\n                  <jats:p>Conclusion\u2002Sago seed nodules on pleura have a high positive predictive value for tuberculous pleurisy. In high endemic countries patients with this finding on thoracoscopy can be commenced on anti-tuberculous treatment before histopathology or culture results are
