HEIDARI, B.; BIJANI, K.; EISSAZADEH, M.  and  HEIDARI, P.. Exudative pleural effusion: effectiveness of pleural fluid analysis and pleural biopsy. East. Mediterr. health j. [online]. 2007, vol.13, n.4, pp. 765-773. ISSN 1020-3397.

The study compared pleural fluid analysis and pleural biopsy in the diagnosis of 100 patients with exudative pleural effusion (PE) in Babol, Islamic Republic of Iran. Tuberculous pleurisy and malignant pleural effusion were confirmed by the identification of acid-fast bacilli from body fluids or tumour cells from tissue specimens. Malignant diseases and tuberculosis were the causes of exudative PE in 43% and 33% of patients respectively. The diagnostic sensitivity of pleural biopsy in patients with tuberculous PE and malignant PE was 70% and 54%, and the diagnostic sensitivity of pleural fluid analysis was 33% and 70% respectively. Combined pleural biopsy and pleural fluid analysis were positive in 97% of tuberculous PE cases and 91% of malignant PE.
