An 82-year-old patient was admitted to hospital for progressively worsening dyspnea for 14 days. Huge fluidothorax on the left side was revealed at emergency. A puncture evacuated 1500 ml of significantly haemorrhagic effusion (haemoglobin 35 g/l, haematocrit 0.15). Patient´s haemodynamics was stable. Dyspnea improved after the puncture. On the next day, thoracic drainage was established. Another 1800 ml (haemoglobin level 32 g/l) of fluid was evacuated. The fluid did not form coagula spontaneously when exposed to air.
