In this study, 60 patients who underwent a pleural biopsy by pleuroscopy were studied with unknown causes of pleural effusion. The mean age was (51-/+13.2) and male to female ratio was 4 to 1. There were 36.6% of cases diagnosed with tuberculosis, 23.3% of cases diagnosed with adenocarcinoma. Pleuroscopy failed to reach a diagnosis in 16.6% only.
