RT Journal Article SR Electronic T1 Superior vena cava syndrome caused by encapsulated pleural effusion JF European Respiratory Journal JO Eur Respir J FD European Respiratory Society SP 1675 OP 1677 DO 10.1183/09031936.97.10071675 VO 10 IS 7 A1 CL Lai A1 TT Tsai A1 SC Ko A1 KY Yang A1 RP Perng A1 YM Chen YR 1997 UL http://erj.ersjournals.com/content/10/7/1675.abstract AB Pleural effusion is often a manifestation of the superior vena cava (SVC) syndrome. However, pleural effusion has never been reported to be a cause of the SVC syndrome. We report the case of a 68 yr old male patient who presented with SVC syndrome and respiratory failure, both attributable to an encapsulated pleural effusion over the right upper mediastinum. Simple drainage was performed as a diagnostic and therapeutic procedure. The pleural effusion was confirmed to be a tuberculous empyema. Chest computed tomography (CT) scan is the most appropriate initial diagnostic procedure for superior vena cava syndrome.
