                                 The pleura and pericardium are very close anatomical companions within the thorax. Both contain minimal levels of physiological fluid.  It is quiet common to find combined pleural and pericardial  effusion. While the commonest explanation for combination of pleural and pericardial effusion is inflammation of both  in systemic disorders like polyserositis or malignancy . In cardiac failure also both effusions can  occur explained by raised venous pressure.

But there has always been a curious relationship between these two spaces.

                         Is there a antomical or physiological link between these two spacs ?  In fact a large pleural effusion some times result in sympathetic pericardial  effusion.  Tapping of pleural effusion may regress this pericardial fluid as well.

                         This is purely a clinical observation and needs an explanation .It is  believed , there is  some  non functional lymphatic channels shared between pericardial  and pleural spaces.This may get opened up in pathology of either of them.
