Diagnostic and therapeutic thoracentesis demonstrated straw-coloured serous pleural fluid (pf) with an exudative biochemical profile (pf protein 53 g/L, pf lactate dehydrogenase 127 U/L), while cytology revealed scattered lymphocytes. The post-thoracentesis chest radiograph revealed a pleural-based, rounded opacity (figure 1). While CT of the thorax is a pragmatic next step of investigation in this case, due to limited access to urgent CT scans at our centre, a decision was made by the treating team to proceed with medical thoracoscopy (MT).
